- 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
= 100 + 130 + 190 + 230 + 150
= 800
(b)
Number of students who read at least two storybooks
= 800 - 100 - 130
= 570
Percentage of students who read at least two storybooks
=
570800 x 100%
= 71.25%
≈ 71% (Correct to nearest whole number)
