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