Bryan has 15 less than
117 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 = 17 u
Number of stickers that Bryan has = 1 u - 15
(b)
1 -
117 =
1617 Number of stickers that Adam has = 16 u + 15
(c)
Total number of stickers = 17 u
(d)
Difference in the number of stickers between Adam and Bryan
= (16 u + 15) - (1 u - 15)
= 16 u + 15 - 1 u + 15
= 16 u - 1 u + 15 + 15
= 15 u + 30
Answer(s): (a) 1 u - 15; (b) 16 u + 15; (c) 17 u; (d) 15 u + 30
