Adam has 200 red stickers and blue stickers.
30% of the stickers are blue.
- How many red stickers are there?
- How many less blue stickers than red stickers?
(a)
30% =
30100 =
310 Total number of stickers = 10 u
Number of blue stickers = 3 u
Number of red stickers = 10 u - 3 u = 7 u
10 u = 200
1 u = 200 ÷ 10 = 20
Number of red stickers
= 7 u
= 7 x 20
= 140
(b)
Number of less blue stickers than red stickers
= 7 u - 3 u
= 4 u
= 4 x 20
= 80
Answer(s): (a) 140; (b) 80
