Fill in the blanks in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Adam, Bryan and Charlie have some stickers.
Charlie has
56 as many as Adam.
Bryan has 20 more than Charlie.
Let the number of stickers that Adam has be 6 u.
- Number of stickers that Charlie has = _____
- Number of stickers that Bryan has = _____
- Total number of stickers = _____
- Number of stickers that Adam has more than Bryan = _____
(a)
Let the number of stickers that Adam has = 6 u
Number of stickers that Charlie has = 5 u
(b)
Number of stickers that Bryan has = 5 u + 20
(c)
Total number of stickers
= 6 u + 5 u + 5 u + 20
= 16 u + 20
(d)
Number of stickers that Adam has more than Bryan
= 6 u - (5 u + 20)
= 6 u - 5 u - 20
= 1 u - 20
Answer(s): (a) 5 u; (b) 5 u + 20; (c) 16 u + 20; (d) 1 u - 20
