Question

Divide $14÷\frac{7}{2}$ to unlock the card and save Mars.

• A. 3
• B. 4
• C. $\frac{1}{4}$

Answer 1

The correct option is B 4

We can write 14 as $\frac{14}{1}$
$14÷\frac{7}{2}=\frac{14}{1}÷\frac{7}{2}$

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

$\frac{14}{1}÷\frac{7}{2}=\frac{14}{1}\times \frac{2}{7}$

$=\frac{14\times 2}{1\times 7}$

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

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

$=4$

Hence, $14÷\frac{7}{2}=4$
