Answer 2

As per the details provided in the question.

In the above question, we have the details as follow.

The given data is ratio 1 hours : 40 minutes .

We have to find the simplest for of given expression.

Thus, first we have to convert 1 hours in minutes

1 hours = 60 minutes,

So, the ratio is as follow,

$=\frac{60}{40}$

we are dividing both the ratio with 10 we get,

$=\frac{\frac{60}{10} }{\frac{40}{10} } \\=\frac{6}{4}$

Now both numerator and denominator is divided by 2 we get,

$=\frac{\frac{6}{2} }{\frac{4}{2} } \\=\frac{3}{2}$

Hence the simplest form of expression is $\frac{3}{2}$.
