Answer 2

Answer:

1 We have 50 students. 50 is the half of 100 because 50x2=100

2 40% is equal to 40/100

3 As we all probably know from fractions if we divide one of the numbers in the fraction, we have to divide with the same number the other one.

4 So, 40/100 is equal to 20/50 because 100/2=50 and 40/2=20

5 20/50 (which is equal to 40/100 or 40%) says that 20 girls are in the class

6 And if we do the subtraction, it’s 50–20=30
