Question

$\frac{4}{20}$ as a decimal is :

• A. 0.4
• B. 0.2
• C. 0.25
• D. 0.4

Answer 1

The correct option is B 0.2

First we split the fraction as $\frac{4}{2}\times \frac{1}{10}$
$\Rightarrow 2\times \frac{1}{10}$
Since the number of zeroes in the denominator is one, we shift the decimal point once to the left
$\therefore$ required decimal is 0.2
