To divide the fraction \( \frac{2}{5} \) by \( \frac{3}{4} \), you can multiply \( \frac{2}{5} \) by the reciprocal of \( \frac{3}{4} \).
The reciprocal of \( \frac{3}{4} \) is \( \frac{4}{3} \).
Now, perform the multiplication:
\[ \frac{2}{5} \div \frac{3}{4} = \frac{2}{5} \times \frac{4}{3} \]
Multiply the numerators and the denominators:
\[ \frac{2 \times 4}{5 \times 3} = \frac{8}{15} \]
So, \( \frac{2}{5} \div \frac{3}{4} = \frac{8}{15} \).
