2) ?/32=1/8

Answer 1

1. B

2. B

Explanation:

To find the missing term, find the scale factor between the fractions - the number which multiplies to one to make the other.

1. 7 x __ = 35

7x 5 = 35 therefore 5 is the scale factor. Multiply 15 x 5 = 75

2. 8 x ___ = 32

8 x 4 - 32 therefore the scale factor is 4. Multiply 1 x 4 = 4.
