13 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 = 3 u
Number of stickers that Adam has = 1 u + 15
(b)
1 -
13 =
23 Number of stickers that Bryan has = 2 u - 15
(c)
Total number of stickers = 3 u
(d)
Difference in the number of stickers between Bryan and Adam
= (2 u - 15) - (1 u + 15)
= 2 u - 15 - 1 u - 15
= 2 u - 1 u - 15 - 15
= 1 u - 30
Answer(s): (a) 1 u + 15; (b) 2 u - 15; (c) 3 u; (d) 1 u - 30
