Question

What fraction of an hour is $40$ minutes ?

Answer 1

Convert hour into minutes and compare the similar quantities to obtain a fraction

We know that,

$1$ hour $=$$60$ minutes

$\Rightarrow$ $\frac{1}{60}$ hour$=$$1$minute

$\Rightarrow$$\frac{1}{60}\times 40$ hour$=$$40$ minutes

$\Rightarrow$ $40$ minutes$=$$\frac{2}{3}$ hour

Hence, $40$ minutes are ${\left(\frac{2}{3}\right)}^{rd}$ of an hour.
