Question

70% of the students in a school are boys and the number of girls is 504. Find the number of boys in the school.

Answer 1

Answer:

1176 boys

Step-by-step explanation:

Find the percentage of girls:

boys = 70%

girls = 100 - 70 = 30%

Find the number of boys:

Girls = 30%

Girls = 504

30% = 504

1% = 504 ÷ 30 = 16.8

70% = 168 x 70 = 1176

Answer: There are 1176 boys

Answer 2

let the total no. of children be X so the girls are 30% of X= 504
X= 504*(100/30)
X= 1680
so we now wanna find 70% of X because boys =70%
70/100(1680)


= 1176
