Answer 2

In context to question asked,

We have to determine the ratio of 1/2 hours to 45 minutes.

As we know that,

Ratio of two or more quantity are determined only if the both quantities have similar units.

So, for determining the ratio we will convert 1/2 hour into minutes.

As we know that,

There are 60 minutes in 1 Hour.

So, there will be $60 \times \frac{1}{2} = 30\:minutes$ in 1/2 Hours.

So, now determining the ratio between 30 minutes and 45 minutes.

We will get,

$\frac{30}{45} = \frac{2}{3}$

Hence, the ratio of 1/2 hour to 45 minutes will be 2:3.
