Question

The ratio of boys to girls taking geometry this year is 27:31. If 246 students are ebrolled in geometry this year, approximately how many of them are boys and how many of them are girls?

Answer 1

115 boys

131 girls

Explanation:

Given data

The given ratio= 27:31

The sum of the ratio = 27+31= 58

The total number of students taking geometry= 246

Let us apply the part to all method

let the number of boys be x

27/58= x/246

cross multiply

58*x= 246*27

58x=6642

x= 6642/58

x=114.5

Hence the number of boys is 115

Thefore, the number of girsl= 246-115= 131
