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 Bryan has is 21 less 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)
35 of Bryan's stickers → 6 u - 21
15 of Bryan's stickers → (6 u - 21) ÷ 3 = 2 u - 7
55 of Bryan's stickers → 5 x (2 u - 7) = 10 u - 35
Number of Bryan's stickers = 10 u - 35
(c)
Total number of stickers
= 7 u + 10 u - 35
= 17 u - 35
(d)
Difference in the number of stickers between Bryan and Adam
= (10 u - 35) - 7 u
= 10 u - 7 u - 35
= 3 u - 35
Answer(s): (a) 7 u; (b) 10 u - 35; (c) 17 u - 35; (d) 3 u - 35
