Adam has 3100 stickers altogether.
There are 900 blue stickers and
900 green stickers more than blue stickers.
The rest are red stickers.
- How many red stickers does Adam has?
- how many less red stickers than green stickers does Adam have?
(a)
Number of blue stickers = 900
Number of green stickers = 900 + 900 = 1800
Total number of blue and green stickers
= 900 + 1800
= 2700
Number of red stickers
= 3100 - 2700
= 400
(b)
Number of less red stickers than green stickers
= 1800 - 400
= 1400
Answer(s): (a) 400; (b) 1400
