Adam and Bryan have 60 stickers.
Adam has 40 less stickers than Bryan.
- Number of stickers that Adam has = _____
- Number of stickers that Bryan has = _____
- Total number of stickers = _____
- 1 u = _____
Choose the person who has less stickers to be 1 u.
Adam has 40 less stickers than Bryan.
So, Adam has less stickers.
(a)
Number of stickers that Adam has = 1 u
(b)
Number of stickers that Bryan has = 1 u + 40
(c)
Total number of stickers
= 1 u + 1 u + 40
= 2 u + 40
(d)
Total number of stickers = 60
2 u + 40 = 60
2 u = 60 - 40 = 20
1 u = 20 ÷ 2 = 10
Answer(s): (a) 1 u; (b) 1 u + 40; (c) 2 u + 40; (d) 10
