Question

in 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:

Let "x" be the total no. of students. But we are given that the number of girls in the school is 775. Thus, the number of boys in school is 620.

Answer 2

Let the total number of students be x

(4/9)x + 775 = x

(4x/9) - x = -775

x - (4x/9) = 775

(5/9)x = 775

x = 155×9 = 1395

Total number of students = 1395

So, the number of boys = 1395 - 775 = 620

Hope it helps. Thank you.
