For anyone having trouble with this...
I couldn't learn this when I was in middle and high school. I went onto college and found out I was capable of learning this stuff, just not in a standard classroom setting. I now have two degrees, one of which is a mechanical engineering degree. I found myself here because I wanted to brush up on some things for the military ASVAB test when I remembered how difficult this was when I was a kid. So please don't feel stupid if you're having difficulty learning this especially if its your first time. No one is above math.

thank you very much i feel inspired now
Thanks I feel a lot better about my test

Sal great explanation. Just one correction, at 3:59, ratio of dogs to horses is 1:2 not 1:5
Right, I had to pause there, also. The ratio of dogs to horses 5:10 reduces to 1:2, 1 dog for every 2 horses.
i hope i pass my test for tomorrow

Hey there but how did 5:10 changed into 1:5 shouldn't it be 1:2 ?
yes
Yeah I’m pretty sure the only way to simplify it all the way is to divide both numbers by 5 not 2
right! He said divide both by 5, 10 divided by 5 is 2 not 5.... so it's wrong and he made a mistake?
Thank you I thought I was going crazy lol
Yes, I think he made a mistake
3:27 should’ve been 2 Horses. Correct ratio should be 1:2 or There is 1 dog for every 2 horses.
Yeah that got me sorta confused lol

Don’t think that at least you are trying and are committed
You would be dumb if you didn't try to learn the subject. Stupidity is knowing you're ignorant, but doing nothing about it, while intellect is where you know you're unsure about a subject, but still try to accuire knowledge anyways. Whether the subject is complex, or basic, it's never dumb when you try to learn.

Thank you 1:2 :P
5:44 So basically, if you have a two-digit number that is even and the second digit is zero, you take the number of which it is doubled from?
So let's say 80. I technically have to use 4, correct?

I absolutely HATE ratios. I struggle with even the simplest of them.
i really really feel great watching this video he made it so simple I NEVER LIKED RATIOS but i am very confident fire a foundation GCSE question if you are dtuck when you come across one
10 divided by 5 is 2 not 5.
Ratio of horses to dogs is 2:1, ratio of dogs to horses is 1:2.
The numbers don’t change just because you change the order of the ratio.
I think you’re a bit tired Khan! Have a rest from teaching thousands of people single handedly!

I wish khan academy would do ACT practice, topic-wise, like that of the SAT, because I'm literally plummeting and I don't have 1000 dollars to pay for for-profit educational organizations. I surely will be donating a lot to khan academy for their indelible efforts. What I like most about the khan academy practice questions is that they are topic-oriented and Don't seem to end. It would also be great if the programmers made a screen time restriction that you can freely adjust to prevent you from zoning out on your phone and kind of forcing you to finish the daily 120 questions. That would be a dream come true. I surely will be programming something like that for the ACT. It will be hard but worth it if it's going to help someone out of the trauma I'm going through rn, Being unable to find topic-oriented material.

Why did it say 1:2 even tho it was clearly 1:5 he was right the first time he incorrected himself poor Khan
actuallt it is 1:2. 5:10, the you divide them by 5 and you get 1:2
ratio of dogs to horses is 5:10 which is equal to 1:2. Where did you get 1:5?
