Adam has 1800 stickers altogether.
There are 400 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 = 400
Number of green stickers = 400 + 900 = 1300
Total number of blue and green stickers
= 400 + 1300
= 1700
Number of red stickers
= 1800 - 1700
= 100
(b)
Number of less red stickers than green stickers
= 1300 - 100
= 1200
Answer(s): (a) 100; (b) 1200
