So,
In order to find numbers that are in between 3/8 and 6/7, Lucy must make common denominators first.
LCM of 8 and 7: 56
Multiply each fraction by the appropriate form of 1:
[tex] \frac{3}{8} * \frac{7}{7}\ AND \ \frac{6}{7} * \frac{8}{8} [/tex]
[tex] \frac{21}{56}\ AND\ \frac{48}{56} [/tex]
We can immediately see that any fraction with a numerator between 21 and 48 and a denominator of 56 will fit into the criteria Lucy needs.
The correct option is B.
