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.​

Clara · Answer

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.
