Fill in the blanks with units (Eg 1 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have 180 stickers.
Adam has 80 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 80 more stickers than Bryan.
So, Bryan has less stickers.
(a)
Number of stickers that Adam has = 1 u + 80
(b)
Number of stickers that Bryan has = 1 u
(c)
Total number of stickers
= 1 u + 80 + 1 u
= 2 u + 80
(d)
Total number of stickers = 180
2 u + 80 = 180
2 u = 180 - 80 = 100
1u = 100 ÷ 2 = 50
Answer(s): (a) 1 u + 80 or 80 + 1 u; (b) 1u; (c) 2 u + 80 or 80 + 2 u; (d) 50
