Thank God it's free
why does this channel have everything i need!! It is seriously underrated!!
Ah thank you so much!! 😊
Bro has acctually saved my skin those I smt ruffled with a lot but he explains it better than teachers lol
Hm
Yeah!❤
How is this difficult? the way you explained it made it so simple
Ya you 'r right
Better tutorial
really 👍
why u lying
its still confusing but he still made things easier to understand ig
This video was brilliant! Helped heaps with my homeschooling. You explained it in a way that was clear, informative and easy to follow.
screw the 10 people who disliked😤! he made it so simple and understandable! this helped alot.. thanks man ur a GOAT
Glad you enjoyed the video even if others didn't 👍
A simpler version of this is lets Say you have 0.6 (recurring) add 6 in the top as the fraction, and if since theres only one number after the decimal you will add one 9 if you have more then one let's say .27 you add two 9 for the bottom number and if you can reduce it (I recommend TI-30Xa calculator) using the a b/c button and then clicking the = button to simplify it
Good luck peeps for tmr
I just found this channel at the right moment, I'm recently in 9th class and figured you make science and maths educational content for 9th grade, i think God wanted me to find this channel as i wanted a channel to keep studying in my summer vacations to be 1 step ahead of my class
Me too
This guy is actually underrated! The way he explain the things is awesome!
I love Math Genie, but their video of Recurring decimals to fractions got me confused
This video is great! Thanks!
Thank you your a lifesaver i know what to do now
Glad to hear it 😁
Bro thank you so much, I have my maths yearly in 6 hrs and I was revising indices and I came across this video and it explained it so well, thank you.
Best of luck Srijan! 🤞
Oh
Bro my teachers were horrible but this 6 minute video helped so much, ur a life saver my exam was a week ago and I got an A+, this literally helped so much, you deserve over a million subs
I really like this video! it helps me alot with my homework!! Thank you soooo muchhhh
fr
Perfectly explained yet again, thank you
Thanks for the teaching
I love this channel it is so much better than the old one I used to watch ❤
How about if the left side of the decimal point has number instead of zero , how do you convert into fraction ????
Thanks sir, ur very helpful!!
Ig this is the first time on TH-cam, that I have seen a study vid and commented with a “sir”, so you are just toooo good!!!!
I am proud to tell you, your explanation needs a chef kiss ❤
The best TH-cam mathematician
am I the only one who noticed this but incognito means unknown and their channels name means known there for to be known and they hell are being known and they are helping thousands I dare say millions of students in their life with 5-minute videos thank you for your effort you are the reason I passed
@notsomeone special no I'm still in grade 9 just normal exams though you?
@notsomeone special i hope it went well was it hard
JUST FOUND MY NEW FAV CHANNEL AS A 9THGRADER FOR MATHS(TYSMMM U R AN AMAZING TEACHER)
i discovered a more easier methodd and it is faster too!
Great video!!!
Really great explanation
Thanks very much for ur efforts....😊
Literal life saver 🙏🏼🙏🏼🙏🏼
Here's a easier process
. .
0.474 as fraction
We will the the full no. Then the no. That do not have recurring we will subtract from that no. Underneath that for each recurring one 9 will come
I.E. -->
474-0
_______
999
Ans 474/999
you are amazing my test is 2 weeks from now and i think i am going to do it well thank you
thanks this helped alot i forgot how to do this but now it makes full sense
Hey Cognito, are there GCSE maths videos for higher or foundation
I think higher
:)
It depends on the curriculum just check the spec you are doing,
I am doing edexcel IGcse maths a higher tier so these are basically irrelevant because the book has more random stuff in it and even calculus whilst gcse and IGcse Cambridge are normal
THIS WAS GREAT! THANK YOU SO MUCH!!!
thanks well explained
In the first step, how come you get 23.3 (recurring) when you multiply 2.3 by 10. Shouldn't you get 23? I will appreciate if you explain that bit.
Recruiting just means the number goes on forever, so the space after the decimal point will always have a three no matter how much you multiply it
It isnt 2.3, it is 2.33333333333333 and so on. The dot represents the number going on until infinity
Bro, i was stuck at a problem like this from 3 days now thanks to you i know how to solve
Thanks Cognito the way in which you explained it made it way more simpler and easier and also helped me in my Year 11 IGCSE academic year thanks a lot once again
thanks boss
Thanks alot it got clear now.
will you please solve 9.019 to fraction where dots on 1 & 9
Maths exam tomorrow god bless this man👏
This was really helpful thank you.
i discovered a more easier methodd and it is faster too
4:23 wont 100r be 23.23 instead of 23.3?
Not in this case, because it’s only the 3 that is recurring, not both the 2 and 3!
@@Cognitoedu shouldnt the recurring sighn be on the first three on the the 23.3 since it moved up ?
@@abdulrahmanakinade2879 the recurring symbol should only be placed on decimals. Since the first 3 is a whole number, the next 3 will have the recurring symbol.
My guy 2 is not recuring
Thanks a bunch!
Thank u so much,God bless u
What Cognito told the teachers: Time to retire. Students dont need you anymore. My channel has everything they need to pass their exams
I felt so stupid before this video and now I'm a genius
the best video that i've seen on this topic. thank you!
This is interesting , thank you for simplifying
tysm this helped me a lot
0:23 - 0:42 the number is 0.473473473... and so on "A dot above the first and last digits that recurr"
why can't there be dots on top of all those three numbers? Why just the first and last? They're all recurring right? How am I supposed to know 0.4' 7 3' is 0.473 *473473* instead of 0.473 *4343* ? Only 4 and 3 were dotted so I'm a bit confused. Again many thanks!! 🙏🙏
You only put dots above the first and last digits which recur, because that's how things have historically been done in maths. The idea behind that is to show where the recurring sequence begins and ends... and if you recognise that the dots represent the beginning and end of a sequence, it can be taken as a given that every digit in-between the ones with dots above them are also part of that sequence. This can also save time, since if you have to write a long sequence of recurring digits, you would need to write alot of dots as well using your proposed method, whereas the standard practice allows you to show where the sequence begins and ends with just two dots. No will stop you putting dots above all the recurring digits if you want, but you could lose marks in an exam for that, since that's not the standard practice. If you're having trouble making sense of it, just think of the two dots as 'bookends' to the recurring sequence.
very good i find this very easy
Very good!!
amazing your video really help you talked about what I needed thanks
wow thanks! its so easy now
ur my favourite man ever
THIS IS AMAZING I LOVE YOUR VIDS THANK YOU!!
thanks this was really helpful
thx this really help alot
Thank you legend
IM GONNA CRY I FINALLY UNDERSTOOD IT JAJAJJAJA
Gud vid
good way to find answer
Very helpful 👍👍👍
Thanks, guys. This really helped.
Thx so much
yk what im subscribing bro this vid is excellent
Thanks 😊 🙏
How did you know you had to put 473 next to 999r?
Because that's the value he got when he subtracted the bigger r value with the smaller one
Real g so got it easy now after
❤❤❤❤,
Excellent, tyyy 😘
Oh thank you my dyspraxic ass could not understand this
You are the best! **********
If i got the second answer as 23 over 99 is it still right
So easy 😁
can anyone explain how dividing 21 by 90 does not actually do anything different to the 21
because its a fraction
To make it into a fraction
What is the question says express 0.6 recurring as a fraction of
r = 0.6 (recur)
x10
10 r = 6.6 (recur)
x10
100 r = 66.6 (recur)
larger - smaller =
100 -10 = 90 66.6 - 6.6 = 60
60/90 = 2/3
(/30 btw)
sorry for the super late response, didn't see this earlier
LIFE SAVER TYY
How funny, your last example was my question.
ily bro
Can't we just divided ?
Sir, in 0.473, 7 is also repeating, so why didn't you put the dot above 7 ? you only put the dot above 4 and 3, why ?
Because the dot notation only should come at the first and last digit
It is because you put the dot on the first number of the pattern and last number so automatically 7 is also in the pattern
not sure how your meant to know what number comes after when multiplying each time. for example: how do you know that 4.734 x10 makes 47.347
calculator 💀
Cuz thats the rule in Maths, u should have learned this earlier
THANK YOUU
thanks
WOW!! PERFECT...
W VID DUDE 🎉🎉🎉🎉🎉🎉🎉❤❤❤❤❤❤❤
I didn’t understand the last equation why 100 and 10 ?
To the KES gents writing Tmr
Why don't you add a dot above the second number?
It’s been 2 months but basically you only put dots above the first and last digits that recur. Think of it like this, when there is more than 1 dot above the numbers think of them like brackets; everything inside them will reoccur. Eg
. .
0.24687 will recur like 0.246872468724687…….and so on
@@_everlark_ done my GCSEs now but thanks 🫡
I’m binging cognito lol
Why is it that the denominator always only have 9 digits
in the last video u should if you want to convert a fraction into a recurring decimal it has to be over 9, 99, 999
so just use that logic, example: 0.951=951/999 😅😅😅
1:30hours idk anything 6:19minutes Ik the whole thing
I. LOVE. YOU.

wow
meowww 🥺🥺🥺
