(a)
90°360° = 25% of stationery in Box L
Percentage of pencils in Box L = 25%
Percentage of highlighters in Box L
= 100% - 45% - 25%
= 30%
(b)
Percentage of highlighters in Box M

= 35%
Fraction of stationery in Box M that is highlighters
= 35100
=
720 (c)
30% of stationery in Box L = 60
1% of stationery in Box L = 60 ÷ 30 = 2
100% of the stationery in Box L = 100 x 2 = 200
Number of stationery in Box M
= 200 ÷ 2
= 100
100% of stationery in Box M = 100
1% of stationery in Box L = 100 ÷ 100 = 1
35% of stationery in Box L = 35 x 1 = 35
Number of highlighters in Box M = 35
Answer(s): (a) 30%; (b)
720; (c) 35
