What is the decimal form of $\frac{1}{50}$?

• A. 0.2
• B. 0.002
• C. 0.02
• D. 0.0002

Answer 1

The correct option is C 0.02

On factorising the denominator,
$\frac{1}{50}$ = $\frac{1}{5^2\times 2}$

To convert a fraction into decimal form, make the denominator in terms of multiples of 10.

$\frac{1}{5^2\times 2}=\frac{1}{5^2\times 2}\times \frac{2}{2}=\frac{2}{5^2\times 2^2}=\frac{2}{{10}^2}=\frac{2}{100}=0.02$
