Question 4 (j)

Write the following as decimal:

$3\frac{3}{5}$

Answer 1

$3\frac{3}{5}=\frac{5\times 3+3}{5}$
$=\frac{18}{5}$ (converting mixed fraction into improper fraction)
$=\frac{18\times 2}{5\times 2}$ (multiplying numerator and denominator by 2)
$=\frac{36}{10}=\frac{30+6}{10}$
$=\frac{3\text{/}0}{1\text{/}0}+\frac{6}{10}$ (dividing numerator and denominator by 10)
$=3+0.6=3.6$
