Fill in the blanks in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Charlie, Bryan and Adam have some stickers.
Adam has
710 as many as Charlie.
Bryan has 10 less stickers than Adam.
Let the number of stickers that Charlie has be 10 u.
- Number of stickers that Adam has = _____
- Number of stickers that Bryan has = _____
- Total number of stickers = _____
- Number of stickers that Charlie has more than Bryan = _____
(a)
Let the number of stickers that Charlie has = 10 u
Number of stickers that Adam has = 7 u
(b)
Number of stickers that Bryan has = 7 u - 10
(c)
Total number of stickers
= 10 u + 7 u + 7 u - 10
= 24 u - 10
(d)
Number of stickers that Charlie has more than Bryan
= 10 u - (7 u - 10)
= 10 u - 7 u + 10
= 3 u + 10
Answer(s): (a) 7 u; (b) 7 u - 10; (c) 24 u - 10; (d) 3 u + 10
