Question

The enrolment of our school is 800. If 35 % are girls

a. What fraction are girls?
b. What fraction are boys?

Answer 1

a. 280/800 (or 7/20 simplified)

b. 520/800 (or 13/20 simplified)

Explanation:

a. 800 × 0.35 = 280

Fraction of girls = total girls/total enrollment = 280/800 (or 7/20 simplified)

b. Total boys = Total enrollment - total girls = 800 - 280 = 520

Fraction of boys = total boys/total enrollment = 520/800 (or 13/20 simplified)

Answer 2

a 7/20. B 13/20

Explanation:

800 X 35% = 280

280/800=7/20
