Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
Bryan has 13 less than
13 of the stickers.
- Number of stickers that Bryan has = ___________
- Number of stickers that Adam has = ___________
- Total number of stickers = ___________
- Difference in the number of stickers between Adam and Bryan = ___________
(a)
Change fraction into units.
Total number of stickers = 3 u
Number of stickers that Bryan has = 1 u - 13
(b)
1 -
13 =
23 Number of stickers that Adam has = 2 u + 13
(c)
Total number of stickers = 3 u
(d)
Difference in the number of stickers between Adam and Bryan
= (2 u + 13) - (1 u - 13)
= 2 u + 13 - 1 u + 13
= 2 u - 1 u + 13 + 13
= 1 u + 26
Answer(s): (a) 1 u - 13; (b) 2 u + 13; (c) 3 u; (d) 1 u + 26
