Question

in a school 4 by 9 of the students are boys and the no. of girls is 775.find the no. of boys in the school answers plz​

Answer 1

Step-by-step explanation:

4/9 of students = boys

no. of girls = 775

775 + 4/9 x = x

775 = x-(4/9)x

775= 9x- 4x /9

775 = 5x /9

775×9 = 5x

6975 = 5x

x= 1,395

total no. of students in school=x= 1,395

no. of girls + no. of boys = x

775 + no. of boys = 1395

no. of boys = 1395 - 775

no. of boys = 620 boys

plz mark me brainliest⭐

Answer 2

Answer:

part of girls 1-4/9 = 5/9

No. of girls = 775

5/9 of a whole no. = 775

whole = 775÷ 5/9

775 × 9/5 = 1395

total strength of class = 1395

no. of girls = 775/620
