What part of an hour passes from 1:35 pm to 2:15 pm? Solve

Solution:
Given:
[tex]\text{From 1:35pm to 2:15pm}[/tex]The difference between both times is;
[tex]2\colon15-1\colon35=40\text{minutes}[/tex]Hence, as a part of an hour, we convert the minutes to hour as a fraction.
[tex]\begin{gathered} 60\text{minutes}=1\text{hour} \\ \text{Hence,} \\ 40\text{minutes}=\frac{40}{60} \\ =\frac{2}{3}hr \end{gathered}[/tex]Therefore,
[tex]\frac{2}{3}\text{ of an hour passes from 1:35pm to 2:15pm}[/tex]
