Name an equivalent ratio for 2/4 with a denominator of 24.

Okay, so your denominator is the number at the bottom. You want your denominator to be 24.

2 over 4 = X over 24. 

So first you need to know that 4 multiplied by 6 is 24. So then you need to multiply your numerator, the top number by 6 as well. 

2 multiplied by 6 = 12.

12/24 is your answer
