Question

find the simplest form of 1 hour 15 minutes : 30 minutes​

Answer 1

In context to question asked,

We have to determine the simplest form of 1 hour 15 minutes : 30 minutes​

As we know that,

There are 60 minutes in 1 Hr.

So, converting 1 Hr 15 minutes in minutes,

We will get,

$1\:Hr\:15\:min. = 60+15 = 75\:min.$

So, ratio of 75 min. to 30 min. will be,

$=\frac{75}{30}=\frac{5}{2}$

Hence, $\frac{5}{2}$ is simplest form of 1 hour 15 minutes : 30 minutes​
