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 6 more than
411 of what Adam has.
Let
411 of Adam's stickers be 4 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.
411 of Adam's stickers → 4 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 → 4 u + 6
19 of Bryan's stickers → (4 u + 6) ÷ 2 = 2 u + 3
99 of Bryan's stickers → 9 x (2 u + 3) = 18 u + 27
Number of Bryan's stickers = 18 u + 27
(c)
Total number of stickers
= 11 u + 18 u + 27
= 29 u + 27
(d)
Difference in the number of stickers between Bryan and Adam
= (18 u + 27) - 11 u
= 18 u - 11 u + 27
= 7 u + 27
Answer(s): (a) 11 u; (b) 18 u + 27; (c) 29 u + 27; (d) 7 u + 27
