Answer:
3/8 chocolate chips
Explanation:
1/2 needs to have the same denominator as 7/8
2 * 4 = 8 (denominator) but what you do for the denominator has to apply for the numerator.
1 * 4 = 4 (numerator)
so now you successfully converted 1/2 to 4/8.
Now you solve, total - items you have = how much you need
7/8 - 4/8 = 3/8
