Question

2.2 The ratio of the number of boys to the number of girls in a grade 8 class is 4: 5. If there are 36 learners altogether, how many boys and girls are in the grade 8 class?​

Answer 1

boys : girls = 4 : 5

boys + girls = 36 (total comparison = 4+5=9)

boys = 4/9 x 36 = 16

girls = 5/9 x 36 = 20
