Question

Find each of the following ratios in the simplest form.
$48minutesto1hour$

Answer 1

$48$minutes$:1$hour

$=48$minutes$:1\times 60$minutes since $1$hour$=60$minutes

$=48:60$

$=6\times 8:6\times 10$

$=8:10$

$=2\times 4:2\times 5$

$=4:5$

$\therefore$ the simplest form of $48$minutes$:1$hour is $4:5$
