Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
38 of the stickers that Bryan has is 9 more than
37 of what Adam has.
Let
37 of Adam's stickers be 3 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.
37 of Adam's stickers → 3 u
17 of Adam's stickers → 1 u
77 of Adam's stickers → 7 u
Number of Adam's stickers = 7 u
(b)
38 of Bryan's stickers → 3 u + 9
18 of Bryan's stickers → (3 u + 9) ÷ 3 = 1 u + 3
88 of Bryan's stickers → 8 x (1 u + 3) = 8 u + 24
Number of Bryan's stickers = 8 u + 24
(c)
Total number of stickers
= 7 u + 8 u + 24
= 15 u + 24
(d)
Difference in the number of stickers between Bryan and Adam
= (8 u + 24) - 7 u
= 8 u - 7 u + 24
= 1 u + 24
Answer(s): (a) 7 u; (b) 8 u + 24; (c) 15 u + 24; (d) 1 u + 24
