What fraction of 9 3/8 is 4 3/8 ? (a) 3/8 (b) 7/15 (c) 5/9 (d) 315/8

Hello!

To solve this, I would convert to improper fractions. This is done by multiplying the integer with the denominator and adding it to the numerator.

9 3/8: 9*8+3=72+3=75

4 3/8: 4*8+3=32+3=35

So the improper fractions therefore are 75/8 and 35/8.

Now to see what fractions of each other they are, you can just divide the numerators because the denominators cancel each other out.

35/75 = 7/15

So your answer would be 7/15, or B.

Hope this helped!
