Question

Express the given ratios in their simplest forms:
$2$ hour $30$ minutes: $60$ minutes

Answer 1

2 hour 30 minutes : 60 minutes

1 hour = 60 minutes

2 hour = $2\times 60$ minutes = 120 minutes

2 hour 30 minutes = 120 minutes + 30 minutes

= 150 minutes

150 minutes : 60 minutes

$\frac{150}{60}=\frac{5}{2}$

2 hours 30 minutes : 60 minutes = 5:2
