Answer:
In the class, the total number of students should be known.
There are 45 boys and 30 girls, hence the total number of students is 75.
In order to know the percentage of girls in this class, the number of girls has to be divided by the total number of students and expressed as a percentage, that is multiplying it by 100%
The percentage of girls in the class is
(Number of girls/Total number of students) x 100%
(30/75)x 100%
30/75 = 0.4
0.4 x 100%
40%
