$\text{Divide:}3÷\frac{3}{8}$

• A. 6
• B. 8
• C. $\frac{1}{8}$
• D. $\frac{1}{6}$

Answer 1

The correct option is B 8

We can write 3 as $\frac{3}{1}$

$3÷\frac{3}{8}=\frac{3}{1}÷\frac{3}{8}$

Take a reciprocal of the second fraction and multiply with the first fraction as follows

$\frac{3}{1}÷\frac{3}{8}=\frac{3}{1}\times \frac{8}{3}$

$=\frac{3\times 8}{1\times 3}$

$=\frac{3\times 8}{1\times 3}$

$=\frac{8}{1}$

$=8$

Hence, $3÷\frac{3}{8}=8$
