Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
45 of the stickers Adam has is 4 less than
89 of what Bryan has.
Let
89 of Bryan's stickers be 8 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.
89 of Bryan's stickers → 8 u
19 of Bryan's stickers → 1 u
99 of Bryan's stickers → 9 u
Number of Bryan's stickers = 9 u
(b)
45 of Adam's stickers → 8 u - 4
15 of Adam's stickers → (8 u - 4) ÷ 4 = 2 u - 1
55 of Adam's stickers → 5 x (2 u - 1) = 10 u - 5
Number of Adam's stickers = 10 u - 5
(c)
Total number of stickers
= 9 u + 10 u - 5
= 19 u - 5
(d)
Difference in the number of stickers between Adam and Bryan
= (10 u - 5) - 9 u
= 10 u - 9 u - 5
= 1 u - 5
Answer(s): (a) 9 u; (b) 10 u - 5; (c) 19 u - 5; (d) 1 u - 5
