10:14, 15:21, 20,28
All you need to do when finding equal ratios is multiply both sides by the same number, In this case you could multiply both sides by 2 and get 10:14 or multiply both sides by 10 and get 50:70. The concept is quite easy.
Hope this helps

Neither of those numbers is a prime number, as both are divisible by 3. It's easy to tell when a number is divisible by three, because all you have to do is add up all the individual numbers that make up the big number, and if THAT number is divisible by 3, then so is the big number.
1 + 1 + 1 = 3
3 is obviously divisible by 3, so no further steps need to be taken here.
2 + 1 + 5 + 1 = 9
9 is also divisible by 3.
Neither of those numbers is prime.
Hope that helped! =)
