Adam has 13 less than
120 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 = 20 u
Number of stickers that Adam has = 1 u - 13
(b)
1 -
120 =
1920 Number of stickers that Bryan has = 19 u + 13
(c)
Total number of stickers = 20 u
(d)
Difference in the number of stickers between Bryan and Adam
= (19 u + 13) - (1 u - 13)
= 19 u + 13 - 1 u + 13
= 19 u - 1 u + 13 + 13
= 18 u + 26
Answer(s): (a) 1 u - 13; (b) 19 u + 13; (c) 20 u; (d) 18 u + 26
