- What percentage of the students in the school read at least two storybooks? (Give your answer correct to the nearest whole number.)
(a)
Number of students in the school
= 280 + 140 + 160 + 270 + 110
= 960
(b)
Number of students who read at least two storybooks
= 960 - 280 - 140
= 540
Percentage of students who read at least two storybooks
=
540960 x 100%
= 56.25%
≈ 56% (Correct to nearest whole number)
