Question

Subtracting $\frac{2}{4}$ from $\frac{4}{2}$ gives the result as _____

• A. $\frac{-2}{2}$
• B. $\frac{3}{2}$
• C. $\frac{-2}{2}$
• D. $\frac{-3}{2}$

Answer 1

The correct option is B $\frac{3}{2}$

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
$\frac{6÷2}{4÷2}=\frac{3}{2}$
Therefore,option b is correct
