Adam has 600 blue stickers and red stickers.
25% of the stickers are red.
- How many blue stickers are there?
- How many less red stickers than blue stickers?
(a)
25% =
25100 =
14 Total number of stickers = 4 u
Number of red stickers = 1 u
Number of blue stickers = 4 u - 1 u = 3 u
4 u = 600
1 u = 600 ÷ 4 = 150
Number of blue stickers
= 3 u
= 3 x 150
= 450
(b)
Number of less red stickers than blue stickers
= 3 u - 1 u
= 2 u
= 2 x 150
= 300
Answer(s): (a) 450; (b) 300
