Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
27 of the stickers Adam has is 10 less than
47 of what Bryan has.
Let
47 of Bryan's stickers be 4 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.
47 of Bryan's stickers → 4 u
17 of Bryan's stickers → 1 u
77 of Bryan's stickers → 7 u
Number of Bryan's stickers = 7 u
(b)
27 of Adam's stickers → 4 u - 10
17 of Adam's stickers → (4 u - 10) ÷ 2 = 2 u - 5
77 of Adam's stickers → 7 x (2 u - 5) = 14 u - 35
Number of Adam's stickers = 14 u - 35
(c)
Total number of stickers
= 7 u + 14 u - 35
= 21 u - 35
(d)
Difference in the number of stickers between Adam and Bryan
= (14 u - 35) - 7 u
= 14 u - 7 u - 35
= 7 u - 35
Answer(s): (a) 7 u; (b) 14 u - 35; (c) 21 u - 35; (d) 7 u - 35
