Fill in the blanks with units (Eg 1 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have 160 stickers.
Adam has 30 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 30 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 + 30
(c)
Total number of stickers
= 1 u + 1 u + 30
= 2 u + 30
(d)
Total number of stickers = 160
2 u + 30 = 160
2 u = 160 - 30 = 130
1 u = 130 ÷ 2 = 65
Answer(s): (a) 1 u; (b) 1 u + 30; (c) 2 u + 30; (d) 65
