Question

Express 18% as a fraction.

• A. $\frac{9}{50}$
• B. $\frac{1}{50}$
• C. $\frac{3}{70}$
• D. $\frac{18}{50}$

Answer 1

The correct option is A $\frac{9}{50}$

A percent is 1 part out of 100.
$\Rightarrow 1\%=\frac{1}{100}$
$\therefore 18\%=18\times \frac{1}{100}=\frac{18}{1}\times \frac{1}{100}=\frac{18\times 1}{1\times 100}=\frac{18}{100}$

Simplifying the fraction, we get
$=\frac{2\times 9}{2\times 50}$
Cancel out the common factors, we get
$=\frac{9}{50}$
