Question

Express $1.2$ into fraction in their lowest terms.

Answer 1

Step 1. Write down $1.2$ as divided by 1, i.e. $\frac{1.2}{1}$

Step 2. Multiply both numerator and denominator by $10$ ( as there are $1$ digit after the decimal point.)

$\Rightarrow \frac{1.2\times 10}{1\times 10}=\frac{12}{10}$

Step 3. Simplify the fraction.

$\Rightarrow \frac{12÷2}{10÷2}=\frac{6}{5}$

Hence, $\frac{6}{5}$ is the fraction of decimal $1.2$.
