Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
45 of the stickers Bryan has is 12 less than
89 of what Adam has.
Let
89 of Adam's stickers be 8 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.
89 of Adam's stickers → 8 u
19 of Adam's stickers → 1 u
99 of Adam's stickers → 9 u
Number of Adam's stickers = 9 u
(b)
45 of Bryan's stickers → 8 u - 12
15 of Bryan's stickers → (8 u - 12) ÷ 4 = 2 u - 3
55 of Bryan's stickers → 5 x (2 u - 3) = 10 u - 15
Number of Bryan's stickers = 10 u - 15
(c)
Total number of stickers
= 9 u + 10 u - 15
= 19 u - 15
(d)
Difference in the number of stickers between Bryan and Adam
= (10 u - 15) - 9 u
= 10 u - 9 u - 15
= 1 u - 15
Answer(s): (a) 9 u; (b) 10 u - 15; (c) 19 u - 15; (d) 1 u - 15
