Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
29 of the stickers that Bryan has is 8 more than
811 of what Adam has.
Let
811 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.
811 of Adam's stickers → 8 u
111 of Adam's stickers → 1 u
1111 of Adam's stickers → 11 u
Number of Adam's stickers = 11 u
(b)
29 of Bryan's stickers → 8 u + 8
19 of Bryan's stickers → (8 u + 8) ÷ 2 = 4 u + 4
99 of Bryan's stickers → 9 x (4 u + 4) = 36 u + 36
Number of Bryan's stickers = 36 u + 36
(c)
Total number of stickers
= 11 u + 36 u + 36
= 47 u + 36
(d)
Difference in the number of stickers between Bryan and Adam
= (36 u + 36) - 11 u
= 36 u - 11 u + 36
= 25 u + 36
Answer(s): (a) 11 u; (b) 36 u + 36; (c) 47 u + 36; (d) 25 u + 36
