looks like you need to study percentages.

Also the idea that in math, "of" almost always means "times"
10% of 20 is 0.10 * 20 = 2

To find out how many pupils wear glasses in a class of 20, we need to calculate 10% of 20.

To do this, we can follow these steps:
1. Convert 10% to decimal form by dividing it by 100: 10/100 = 0.10
2. Multiply 0.10 by 20: 0.10 x 20 = 2

So, 2 pupils in the class wear glasses.
