1.)10
Multiply 25/100 with 40 = (25/100)x40 = (25x40)/100 = 10.

2.) 60%
(12/20)x100 = 60

3.) 105%
(100x36.75) divided by 35 = 3,675
3,675 divided by 35 = 105

4.) 40
We are given that 21 boys make up 52.5% of x students in the class. We know that when multiplying x students by 52.5% will yield 21.

Therefore:
x students * 0.525 = 21 students
x students = 21/0.525
x students = 40

5.) 96%
64% is equivalent to 0.64
0.64 x 150 = 96
