$\text{Divide:}10÷\frac{5}{3}$

• A. 4
• B. 5
• C. 6
• D. 7

Answer 1

The correct option is C 6

We can write 10 as $\frac{10}{1}$
$10÷\frac{5}{3}=\frac{10}{1}÷\frac{5}{3}$

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

$\frac{10}{1}÷\frac{5}{3}=\frac{10}{1}\times \frac{3}{5}=\frac{10\times 3}{1\times 5}=\frac{2\times 5\times 3}{1\times 5}=\frac{2\times 3}{1}=6$

Hence, $10÷\frac{5}{3}=6$
