Question

What fraction of an hour is 40 minutes?

Answer 1

We know, 

\(1\) hour = \(60\) minutes

\(40\) minutes of an hour can be expressed as \(\frac{40}{60}\)

This fraction can be reduced further simplified

\(\Rightarrow\frac{(40 ÷ 20)}{ (60 ÷ 20) }= \frac23\) 

and the simplified form gives us \(\frac{2}3\)

Therefore, \(40\) minutes is \(\frac23^{rd}\) of an hour.
