Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
58 of the stickers that Bryan has is 5 less than
56 of what Adam has.
Let
56 of Adam's stickers be 5 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.
56 of Adam's stickers → 5 u
16 of Adam's stickers → 1 u
66 of Adam's stickers → 6 u
Number of Adam's stickers = 6 u
(b)
58 of Bryan's stickers → 5 u - 5
18 of Bryan's stickers → 5 u - 5 = (5 u - 5) ÷ 5 = 1 u - 1
88 of Bryan's stickers → 8 x (1 u - 1) = 8 u - 8
Number of Bryan's stickers = 8 u - 8
(c)
Total number of stickers
= 6 u + 8 u - 8
= 14 u - 8
(d)
Difference in the number of stickers between Bryan and Adam
= (8 u - 8) - 6 u
= 8 u - 6 u - 8
= 2 u - 8
Answer(s): (a) 6 u; (b) 8 u - 8; (c) 14 u - 8 ; (d) 2 u - 8
