Which equation can be used to find N, the distance between 3/8 and 61/64 on the number line?

A. 3/8 - N = 61/64

B. N + 61/64 = 3/8

C. N - 61/64 = 3/8

D. 3/8 + N = 61/64

D

Step-by-step explanation:

Fractions are much easier to compare when they share a single denominator. Multiplying the numerator and denominator both of 3/8 by 8, we get 24/64. Then the distance between 3/8, or 24/64, and 61/64 is:

N = 61/64 - 24/64

Answer D is correct. 3/8 + N = 61/64 is equivalent to the above result.
