If you would like to solve the following equations, you can calculate it using these steps:
1) x% of 125 cm is 87.5 cm
x% * 125 = 87.5
x/100 * 125 = 87.5 /*100/125
x = 87.5 * 100 / 125
x = 70%
2) y% of 132 days is 125.4 days
y% * 132 = 125.4
y/100 * 132 = 125.4 /*100/132
y = 125.4 * 100 / 132
y = 95%
