Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
34 of the stickers Adam has is 24 less 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)
34 of Adam's stickers → 6 u - 24
14 of Adam's stickers → (6 u - 24) ÷ 3 = 2 u - 8
44 of Adam's stickers → 4 x (2 u - 8) = 8 u - 32
Number of Adam's stickers = 8 u - 32
(c)
Total number of stickers
= 7 u + 8 u - 32
= 15 u - 32
(d)
Difference in the number of stickers between Adam and Bryan
= (8 u - 32) - 7 u
= 8 u - 7 u - 32
= 1 u - 32
Answer(s): (a) 7 u; (b) 8 u - 32; (c) 15 u - 32; (d) 1 u - 32
