Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
Bryan has 14 less than
215 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 = 15 u
Number of stickers that Bryan has = 2 u - 14
(b)
1 -
215 =
1315 Number of stickers that Adam has = 13 u + 14
(c)
Total number of stickers = 15 u
(d)
Difference in the number of stickers between Adam and Bryan
= (13 u + 14) - (2 u - 14)
= 13 u + 14 - 2 u + 14
= 13 u - 2 u + 14 + 14
= 11 u + 28
Answer(s): (a) 2 u - 14; (b) 13 u + 14; (c) 15 u; (d) 11 u + 28
