Question

1. $\frac{3}{8}div\frac{2}{5}=$

$\frac{4}{5}$
$\frac{3}{20}$
$\frac{1}{8}$
$\frac{15}{16}$

Explanation:

Step1: Change division to multiplication

Dividing by a fraction is equivalent to multiplying by its reciprocal. So $\frac{3}{8}\div\frac{2}{5}=\frac{3}{8}\times\frac{5}{2}$.

Step2: Multiply numerators and denominators

Multiply the numerators $3\times5 = 15$ and the denominators $8\times2=16$. So $\frac{3}{8}\times\frac{5}{2}=\frac{15}{16}$.

Answer:

$\frac{15}{16}$
