Question

State True of False
Subtracting $\frac{2}{4}$ from $\frac{4}{2}$ gives the result as $\frac{3}{2}$

Open in App

Solution

True
The LCM of denominators 2 and 4 is 4.

$\frac{4}{2} - \frac{2}{4} = \frac{(4 \times 2) - (2 \times 1)}{4} = \frac{8 - 2}{4} = \frac{6}{4}$
Converting this into its equivalent fraction, by dividing the numerator and denominator with 2, we get
$\frac{6 \div 2}{4 \div 2} = \frac{3}{2}$
Therefore,Its true
