2/3, 7/12 and 3/4.
First, let's find a common denominator.
3: 3, 6, 9, 12
4: 4, 8, 12
12: 12
12 it is.
So, we have to multiply each numerator by the amount of numbers the denominator is multiplied to get 12, the common denominator.
3 x 4 = 12 2 x 4 = 8
8/12 is one.
7/12 stays the same.
4 x 3 =12 3 x 3 = 9
9/12 is the last one.
We have made it easy now.
We have 7/12, 8/12 and 9/12.
Pretty easy.
Your answer is
____________
7/12, 8/12, 9/12.
