Question

in section A of having 45 students, 20 are boys. In section B of the same class having 30 students, 15 are boys. Which section has a smaller fraction of boys?

Answer 1

Answer:

Fraction of boys in section A = 20/45 =4/9 = 0.44

Fraction of boys in section B = 15/30 = 1/2 = 0.5

Clearly section A has smaller fraction of boys

Answer 2

Answer:

section A

Step-by-step explanation:

fraction of boys

section A = 20/45 = 4/9

in section B = 15/30 = 1/2

LCM of denominators of each (9,2) = 18

4/9 = 4×18/9×18 = 8/18

1/2 = 1×18/2×18 = 9/18

8/18 < 9/18

hence SectionA has smaller fraction of boys
