Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
35 of the stickers that Bryan has is 9 more than
34 of what Adam has.
Let
34 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.
34 of Adam's stickers → 3 u
14 of Adam's stickers → 1 u
44 of Adam's stickers → 4 u
Number of Adam's stickers = 4 u
(b)
35 of Bryan's stickers → 3 u + 9
15 of Bryan's stickers → (3 u + 9) ÷ 3 = 1 u + 3
55 of Bryan's stickers → 5 x (1 u + 3) = 5 u + 15
Number of Bryan's stickers = 5 u + 15
(c)
Total number of stickers
= 4 u + 5 u + 15
= 9 u + 15
(d)
Difference in the number of stickers between Bryan and Adam
= (5 u + 15) - 4 u
= 5 u - 4 u + 15
= 1 u + 15
Answer(s): (a) 4 u; (b) 5 u + 15; (c) 9 u + 15; (d) 1 u + 15
