Question

Decimal form of $\frac{2}{4}$ is

• A. 0.2
• B. 0.3
• C. 0.5
• D. 0.05

Answer 1

The correct option is C 0.5

To convert $\frac{2}{4}$ into a decimal, we have to divide 2 by 5

The simplest way to divide fractions is to convert the denominators into the power of 10s.

Hence, multiply both the numerator and denominator of $\frac{2}{4}$ with 25 to get a denominator with the power of 10.

$\frac{2}{4}=\frac{2\times 25}{4\times 25}=\frac{50}{100}$

$\because$ Denominator of fraction $\frac{50}{100}$ is 100
$\Rightarrow$ Write the numerator as 50.0

$\Rightarrow$ Denominator have two zeros (100), hence shift the decimal point two places to the left in 50.0 (numerator)
Tens Ones . tenths hundredths $÷$ 100

5	0	.	0
	0	.	5	0

$\therefore \frac{50}{100}=\frac{50.0}{100}=0.50=0.5$
