Answer 2

Given,

No. of students in a school = 5600

Percentage of boys in a school = 45%

Calculation,

No. of boys in a school = 45% of 5600

= 45/100 * 5600

= 45 * 56

= 2520

No. of girls in a school = No. of students - No. of boys

= 5600 - 2520

= 3080 Ans.

Ans.) The number of girls in a school is 3080.
