Answers
Answer:
The total number of girls are 360
Step-by-step explanation:
x is the total children in school
If 45% of the total students are girls
55% of the total students are boys
If the number of boys is 440
55x/100 = 440
x = 440 x 100 /55 = 800
(There are two ways to do this the first one is)
45% are girls
45x/100 = 45 x 800 / 100 = 360
The total number of girls are 360
Another way is
Subtract the total number of student 800 by the total number of boys 440
800 - 440 = 360
The total number of girls are 360

Step-by-step explanation:
Let the number of girls be x.
It is given that 45% of the students are girls.
then,
Percentage of Boys = 100 - 45
= 55 %
It is given that there are 440 boys.
∴The no of boys is given by 440/x * 100 = 55
x = 440/55 * 100
x = 800
∴The no of girls = 800 - 440
= 360
