Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
38 of the stickers that Adam has is 9 more than
67 of what Bryan has.
Let
67 of Bryan's stickers be 6 u.
- 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.
67 of Bryan's stickers → 6 u
17 of Bryan's stickers → 1 u
77 of Bryan's stickers → 7 u
Number of Bryan's stickers = 7 u
(b)
38 of Adam's stickers → 6 u + 9
18 of Adam's stickers → (6 u + 9) ÷ 3 = 2 u + 3
88 of Adam's stickers → 8 x (2 u + 3) = 16 u + 24
Number of Adam's stickers = 16 u + 24
(c)
Total number of stickers
= 7 u + 16 u + 24
= 23 u + 24
(d)
Difference in the number of stickers between Adam and Bryan
= (16 u + 24) - 7 u
= 16 u - 7 u + 24
= 9 u + 24
Answer(s): (a) 7 u; (b) 16 u + 24; (c) 23 u + 24; (d) 9 u + 24
