Adam and Bryan have 140 stickers.
Adam has 20 more stickers than Bryan.
- Number of stickers that Adam has = _____
- Number of stickers that Bryan has = _____
- Total number of stickers = _____
- 1u = _____
Choose the person who has less stickers to be 1 u.
Adam has 20 more stickers than Bryan.
So, Bryan has less stickers.
(a)
Number of stickers that Adam has = 1 u + 20
(b)
Number of stickers that Bryan has = 1 u
(c)
Total number of stickers
= 1 u + 20 + 1 u
= 2 u + 20
(d)
Total number of stickers = 140
2 u + 20 = 140
2 u = 140 - 20 = 120
1u = 120 ÷ 2 = 60
Answer(s): (a) 1 u + 20 or 20 + 1 u; (b) 1u; (c) 2 u + 20 or 20 + 2 u; (d) 60
