Question

in a school, 4/9 of the students are boys and the number of girls is 775. Find the number of boys in the school.​

Answer 1

Answer:

620

Step-by-step explanation:

5 / 9 = 775

Total number of kids is 775 * 9 / 5 = 1395

Thus number of boys = 1395-775 = 620

Answer 2

Answer:

let the total number of students be x.

boys= 4/9×x= 4x/9

girls=775

so. 4x/9 + 775= x

4x/9 - x = -775

4x-9x/9= - 775

-5x = -775×9

-6975

x= - 6975/ -5 = 1395

now boys = 4/9× 1395=620 boys.
