I need help fast with my sons math homework!!!!?

First you find out how many times the bottom number goes into the top #. That wil be your whole number. the bottom number always stays the same so DON'T change the 2. Now, 2 goes into 15 7 times. (2x7=14) But there is still 1 left over that number left over is your top number (numerator). so the answer for 15/2 is 1 and 1/2. BTW, the bottom number is the denominator!
