Question

Find value of X:
$18÷\frac{2}{7}$ = X

Answer 1

We can write 18 as $\frac{18}{1}$
$18÷\frac{2}{7}=\frac{18}{1}÷\frac{2}{7}$

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

$\frac{18}{1}÷\frac{2}{7}=\frac{18}{1}\times \frac{7}{2}$

$=\frac{18\times 7}{1\times 2}$

$=\frac{2\times 9\times 7}{1\times 2}$

$=\frac{9\times 7}{1}$

$=63$

Hence, $18÷\frac{2}{7}=63$
Value of X $=63$
