Question

$\frac{1}{5}\times \frac{3}{4}=$

• A. $\frac{15}{4}$
• B. $\frac{3}{20}$
• C. $\frac{12}{5}$

Answer 1

The correct option is B $\frac{3}{20}$

Step-1: Multiply the numerators and denominators of the fraction.
$\Rightarrow \frac{1}{5}\times \frac{3}{4}=\frac{3}{20}$

Step-2: Factorize the numerator & denominator of the resulting fraction then Identify the common factors on the top and bottom. Cancel the common factors to get the lowest form of a fraction.

$\Rightarrow \frac{1}{5}\times \frac{3}{4}=\frac{1\times 3}{5\times 4}=\frac{3}{20}$

We can see that there is no common factor between 3 and 20.
