Adam has 2100 stickers altogether.
There are 800 blue stickers and
100 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 = 800
Number of green stickers = 800 + 100 = 900
Total number of blue and green stickers
= 800 + 900
= 1700
Number of red stickers
= 2100 - 1700
= 400
(b)
Number of less red stickers than green stickers
= 900 - 400
= 500
Answer(s): (a) 400; (b) 500
