Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
311 of the stickers that Bryan has is 9 less than
38 of what Adam has.
Let
38 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.
38 of Adam's stickers → 3 u
18 of Adam's stickers → 1 u
88 of Adam's stickers → 8 u
Number of Adam's stickers = 8 u
(b)
311 of Bryan's stickers → 3 u - 9
111 of Bryan's stickers → 3 u - 9 = (3 u - 9) ÷ 3 = 1 u - 3
1111 of Bryan's stickers → 11 x (1 u - 3) = 11 u - 33
Number of Bryan's stickers = 11 u - 33
(c)
Total number of stickers
= 8 u + 11 u - 33
= 19 u - 33
(d)
Difference in the number of stickers between Bryan and Adam
= (11 u - 33) - 8 u
= 11 u - 8 u - 33
= 3 u - 33
Answer(s): (a) 8 u; (b) 11 u - 33; (c) 19 u - 33 ; (d) 3 u - 33
