Hello! So, there are 25 students is Mrs. Duggal's class. To find the amount of students that wear glasses in the class, mutliply the number of students (25) by the percentage, in this case 16% (0.16). 25 * 16% (0.16) is 4. So you have a grid that represents 25 squares. Out of those 25 squares, you would shade 4 of them, and that would represent the students that wear glasses.
