在一次调查中，一组学生被问及他们最喜欢的消遣方式。饼图显示了他们的选择。喜欢阅读的学生占总人数的几分之几？用最简分数表示你的答案。 答：___

1. Determine the percentage of students who like shopping and playing games

The 'Shopping' sector has a right-angle symbol, which represents $90^\circ$ out of $360^\circ$, or $25\%$.
The 'Playing games' sector also has a right-angle symbol, representing $25\%$.

2. Calculate the percentage of students who like to read

Percentage for reading = $100\% - 40\% - 25\% - 25\% = 10\%$

3. Convert the percentage to a fraction in its simplest form

Fraction = $\frac{10}{100} = \frac{1}{10}$
