Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
211 of the stickers that Bryan has is 10 more than
49 of what Adam has.
Let
49 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.
49 of Adam's stickers → 4 u
19 of Adam's stickers → 1 u
99 of Adam's stickers → 9 u
Number of Adam's stickers = 9 u
(b)
211 of Bryan's stickers → 4 u + 10
111 of Bryan's stickers → (4 u + 10) ÷ 2 = 2 u + 5
1111 of Bryan's stickers → 11 x (2 u + 5) = 22 u + 55
Number of Bryan's stickers = 22 u + 55
(c)
Total number of stickers
= 9 u + 22 u + 55
= 31 u + 55
(d)
Difference in the number of stickers between Bryan and Adam
= (22 u + 55) - 9 u
= 22 u - 9 u + 55
= 13 u + 55
Answer(s): (a) 9 u; (b) 22 u + 55; (c) 31 u + 55; (d) 13 u + 55
