• im just going to leave this comment here and hope for upvotes
• there are subtitles on most videos, just click the CC at the bottom for "closed captions". is it not on this one?
• I don't get how you get the answer? Great video btw but I mostly don't understand quite a bit of it.
• You get the answer by figuring out what can be multplied by the numbers in the ratios to get your new ratio.
• Me too, and I'm in advanced math and don't understand this!
• I kinda get it but also dont get it.. HELP AHHHH :(
• so it's like this, you have the smaller numbers, 5 and 4. 5 and 4 are just the ratios. Add 5 and 4 together to get 9(The total amount of questions ratio). Then, for the first answer you can see that 4 is multiplied by 2 to get 8. So then you can just take 9 and multiply it by 2. You get 18! Yay! only 1 more question left! Now you have 45 as your hint. If you divide, that's really just 9 times 5. Now that you know that, you can use the 5 and multiply it with 4. Now you have 20! And you are also done!

Hope this helped :D
