Question

$\frac{3}{4}-\frac{1}{5}=$
$\frac{11}{20}$
$\frac{3}{20}$
$\frac{1}{10}$
$2$

Explanation:

Step1: Find a common - denominator

The common denominator of 4 and 5 is \(4\times5 = 20\).

Step2: Rewrite the fractions

\(\frac{3}{4}=\frac{3\times5}{4\times5}=\frac{15}{20}\) and \(\frac{1}{5}=\frac{1\times4}{5\times4}=\frac{4}{20}\).

Step3: Subtract the fractions

\(\frac{3}{4}-\frac{1}{5}=\frac{15}{20}-\frac{4}{20}=\frac{15 - 4}{20}=\frac{11}{20}\)

Answer:

\(\frac{11}{20}\)
