Answer

$\frac{3}{10}$

Work Step by Step

First, we multiply the numerators by each other and the denominators by each other: $\frac{3}{8}\times\frac{12}{15}=\frac{3\times12}{8\times15}=\frac{36}{120}$ Next, we simplify the resultant expression to obtain the answer: $\frac{36}{120}=\frac{12\times3}{40\times3}=\frac{12}{40}=\frac{3\times4}{10\times4}=\frac{3}{10}$
