Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
Adam has 12 more than
112 of the stickers.
- Number of stickers that Adam has = ___________
- Number of stickers that Bryan has = ___________
- Total number of stickers = ___________
- Difference in the number of stickers between Bryan and Adam = ___________
(a)
Change fraction into units.
Total number of stickers = 12 u
Number of stickers that Adam has = 1 u + 12
(b)
1 -
112 =
1112 Number of stickers that Bryan has = 11 u - 12
(c)
Total number of stickers = 12 u
(d)
Difference in the number of stickers between Bryan and Adam
= (11 u - 12) - (1 u + 12)
= 11 u - 12 - 1 u - 12
= 11 u - 1 u - 12 - 12
= 10 u - 24
Answer(s): (a) 1 u + 12; (b) 11 u - 12; (c) 12 u; (d) 10 u - 24
