Question

Convert $5$ hours $45$ minutes in hours as decimals.

Answer 1

Given: $5$ hours $45$ minutes.

Now, we know that,

$1$ hour $=60$ minutes or

$1$ minute $=\frac{1}{60}$ hours

$\therefore 45$ minutes $=\frac{1}{60}\times 45=\frac{3}{4}$

Now,

$\frac{3}{4}=\frac{3}{4}\times \frac{25}{25}=\frac{75}{100}=0.75$

Thus,

$5$ hours $45$ minutes $=5+0.75=5.75$ hours
