Adam has 300 red stickers and blue stickers.
15% of the stickers are blue.
- How many red stickers are there?
- How many less blue stickers than red stickers?
(a)
15% =
15100 =
320 Total number of stickers = 20 u
Number of blue stickers = 3 u
Number of red stickers = 20 u - 3 u = 17 u
20 u = 300
1 u = 300 ÷ 20 = 15
Number of red stickers
= 17 u
= 17 x 15
= 255
(b)
Number of less blue stickers than red stickers
= 17 u - 3 u
= 14 u
= 14 x 15
= 210
Answer(s): (a) 255; (b) 210
