Open in App

Solution

$4 \frac{1}{2} = \frac{2 \times 4 + 1}{4}$
$= \frac{9}{2}$ (converting mixed fraction into improper fraction)
$= \frac{9 \times 5}{2 \times 5}$ (multiplying numerator and denominator by 5)
$= \frac{45}{10} = \frac{40 + 5}{10}$
$= \frac{4 / 0}{1 / 0} + \frac{5}{10}$ (dividing numerator and denominator by 10)
$= 4 + \frac{5}{10} = 4 + 0.5 = 4.5$
