Question 4 (i)

Write the following as decimal:

$\frac{12}{5}$

Answer 1

$\frac{12}{5}$
$=\frac{12\times 2}{5\times 2}$ (multiplying numerator and denominator by 2)
$=\frac{24}{10}=\frac{20+4}{10}$
$=\frac{2\text{/}0}{1\text{/}0}+\frac{4}{10}$ (dividing numerator and denominator by 10)
$=2+0.4=2.4$
