Adam has 800 blue stickers and red stickers.
35% of the stickers are red.
- How many blue stickers are there?
- How many less red stickers than blue stickers?
(a)
35% =
35100 =
720 Total number of stickers = 20 u
Number of red stickers = 7 u
Number of blue stickers = 20 u - 7 u = 13 u
20 u = 800
1 u = 800 ÷ 20 = 40
Number of blue stickers
= 13 u
= 13 x 40
= 520
(b)
Number of less red stickers than blue stickers
= 13 u - 7 u
= 6 u
= 6 x 40
= 240
Answer(s): (a) 520; (b) 240
