Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
37 of the stickers that Bryan has is 9 more than
67 of what Adam has.
Let
67 of Adam's stickers be 6 u.
- 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.
67 of Adam's stickers → 6 u
17 of Adam's stickers → 1 u
77 of Adam's stickers → 7 u
Number of Adam's stickers = 7 u
(b)
37 of Bryan's stickers → 6 u + 9
17 of Bryan's stickers → (6 u + 9) ÷ 3 = 2 u + 3
77 of Bryan's stickers → 7 x (2 u + 3) = 14 u + 21
Number of Bryan's stickers = 14 u + 21
(c)
Total number of stickers
= 7 u + 14 u + 21
= 21 u + 21
(d)
Difference in the number of stickers between Bryan and Adam
= (14 u + 21) - 7 u
= 14 u - 7 u + 21
= 7 u + 21
Answer(s): (a) 7 u; (b) 14 u + 21; (c) 21 u + 21; (d) 7 u + 21
