The Necromancer I hope you get better soon ❤️. I have to be homeschooled and so right now I’m by myself tryin to do my work but I didn’t understand how to do this.
The amount of times youtube has taught me something better than school ever did is frightening. But this is an amazing lesson, super useful especially when my calculator refuses to turn crap into fractions.
Mechanical Engineering Major here (university student). Found this video quite helpful. I never actually learned this is any of my elementery to highschool classes, and I usually just used a calculator to convert the number into a fraction. Being able to do this (first on paper and now in my head) saves a couple of seconds while writing out solutions on homework and on exams for, say, my Fluid Mechanics class. So thank you!!! (Extremely useful when I need to maintain a certain level of precision which is lost on rounding but which also costs a tiny bit of time to regenerate in my calculator from previous steps. it's not much but, when using pipeflow equations for example, it stacks up quickly)
If anyone is stuck on WHY and HOW we got 9. Here is HOW;[10x - x = 10x - 1x= 9x] the missing piece is the #1 no body stated it, everyone here is only paying attention to the fact the it just 9 without actually explaining how we got to 9. Here the WHY remember [x is the same as 1x] #1 is the multiplicative identity in multiplication.
Thank you so much for explaining that! I’m doing an 8th grade summer course and I’m going to be learning 9th grade math next year when I’m in 7th grade(I’m learning two grades ahead), so it’s been really hard for me to understand all of this.
Thanks SOOOOOOOOOOOOOOOOO much, this reeally really really helped.... at first i couldnt understand how they got an answer, but with this, i understand it perfectly! Thanks!
absolutely fantastic explanation in most books they just explain the procedure to solve a particular math problem but you explained how that procedure came

It really helped me a lot.... I haave been finding a way to solve this since my teachers way of solving isn't really clear when i found this vid i am so happy because i onow how to solve all of them yayyyy
Thank you so much. I have a math book that just says .3333 is 1/3 without saying why. Normal conversion of non-repeating was clearly explained, 25%, move decimal to left two places-.25. Then .25 is 25/100 then reduce by the shared divisible number of 25 to get 1/25. But this doesn’t work with repeating decimals and the book didn’t explain why. You’re video is exceptional. I’m now following you. 👏🏾
COLLEGE you say? I’m in 9th grade and I have to know this shit and stuff that’s way harder, my guy you are behind on subject matter, either you are dumb and failed each and every year or you are just American
I find it easier to just use this formula: d/(10^(n)-1), where d is the repeated number as a whole number (For example, for 0.1428571... d is 142857), and n is the number of digits in the repeat (for the same example as last time, n would be 6)
@@clonewarsproductions6454 as a grade 9 student thats best at all subjects but sucks at math i think thats what a student hears when a math teacher talks
Simple. 1/9=.1111111, 1/99=.0101010101 1/999=.001001001001001, exedra. So, whatever the repeating decimal is, count the number of digits that repeat, then write a that number of 9’s repeating. Then, put the 9’s at the bottom of a fraction, with the number that repeats on top. Then, if possible, simplify. You have your fraction.
My son's 11 and 5th grade and learning this. They just introduced decimals and he's already being slammed with this. I like to know how in the world you're in 7th and 8th grade math being 11 but hopefully that means you can grasp this better than we can.
Omg you just saved me!!! Thank you so much! Now, I know how. My prof. kinda explained it in complicated way. Glad that I found this! It's much easier I just wish I saw this earlier. I did wrong solution in one number in my quiz :< nevertheless thank ya so much! Have a great day!!😁
Using this method, we can prove that 0.9999....=1. Let's call the decimal number x. Since there is one repeating digit, multiply x by 10, and subtract x. You will come up with 9.9999...-0.9999=9. Since 10x - x = 9x, and 9x=9, divide both sides by 9, and you will get 9x/9 =9/9. Eliminate the 9's on the left side. You will get x= 9/9, which will simplify to 1. Therefore, 0.9999....=1.
You can write the pattern of a repeating decimal once. The decimal equivalent of 1/3 is 0.33333. You can write it as 0.3, and put a dot or line over the 3. The dot or line will show that it repeats. If more than one digit repeats, we put dots or a long line over the entire repeating pattern. For example, 1/7 is 0.142857... You can put a line over the decimal places. I hope that helps, Robert Wilson!
@@tintintin070 This is exactly why I think college is stupid. Starting witb Peter Abelard, academia has lost its way. The last good thinker was Aristotle. Everything after him has been nearly worthless. I know he thought continuous mathematics was empirical, and believed in irrationality on these grounds. However, if Aristotle were alive today I truly believe that he would falsify his prior beliefs in light of new evidence and advocate making new mathematics that is empirically sound and throw away all the unsound crap. But I also have to say that I don't even consider anyone intelligent unless they have an iq of at least 150, and in reality I really would prefer an iq of at least 160 to even consider anyone worth listening too deeply when they speak. So, obviously, most college graduates and working professionals are below an iq of 160. And yes, I do think lowly of the vast majority of them. Most professors, even, have iq's below 150. And yes, I think lowly of them too. But, my parents are high iq so I have spent my entire life interacting with and arguing with really very intelligent people. So my perspective is skewed and my expectations are through the roof. My dad's iq is 151, for reference. Measured by the Army in the 70's and then again by mensa 10 years later. He never joined mensa. He never graduated college, either. He thought everyone was too stupid to be worth learning anything from, tbh. I share his opinion
+MyWhyU What if the first number of the repeating decimal is 0 for example , 0.0545454... And it says it's equal to 3 over 55. But then it says what decimal could be added to 0.0545454... To get 0.1545454....?

omg thank u 8th grade is so painful
Same ugh
Even math professors were in 8th grade once. I feel your pain. - Professor V.S.
+MyWhyU well as I go on it gets easier but at the same time difficulty increases
Subtracting x from "10 times x" gives you "9 times x". This is what happens when we subtract the fraction from 10 times the fraction.
+MyWhyU What if the first number of the repeating decimal is 0 for example , 0.0545454... And it says it's equal to 3 over 55. But then it says what decimal could be added to 0.0545454... To get 0.1545454....?
I should of seen this before my exam , I got a 3 T.T
what if it’s a negative number
Then it is negative
ignore the negative and solve it. At last write the answer with a negative sign.
Yes just ignore and put itbackwhen you solve it
