Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
38 of the stickers that Bryan has is 9 less than
35 of what Adam has.
Let
35 of Adam's stickers be 3 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.
35 of Adam's stickers → 3 u
15 of Adam's stickers → 1 u
55 of Adam's stickers → 5 u
Number of Adam's stickers = 5 u
(b)
38 of Bryan's stickers → 3 u - 9
18 of Bryan's stickers → 3 u - 9 = (3 u - 9) ÷ 3 = 1 u - 3
88 of Bryan's stickers → 8 x (1 u - 3) = 8 u - 24
Number of Bryan's stickers = 8 u - 24
(c)
Total number of stickers
= 5 u + 8 u - 24
= 13 u - 24
(d)
Difference in the number of stickers between Bryan and Adam
= (8 u - 24) - 5 u
= 8 u - 5 u - 24
= 3 u - 24
Answer(s): (a) 5 u; (b) 8 u - 24; (c) 13 u - 24 ; (d) 3 u - 24
