Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
25 of the stickers that Bryan has is 2 more than
1011 of what Adam has.
Let
1011 of Adam's stickers be 10 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.
1011 of Adam's stickers → 10 u
111 of Adam's stickers → 1 u
1111 of Adam's stickers → 11 u
Number of Adam's stickers = 11 u
(b)
25 of Bryan's stickers → 10 u + 2
15 of Bryan's stickers → (10 u + 2) ÷ 2 = 5 u + 1
55 of Bryan's stickers → 5 x (5 u + 1) = 25 u + 5
Number of Bryan's stickers = 25 u + 5
(c)
Total number of stickers
= 11 u + 25 u + 5
= 36 u + 5
(d)
Difference in the number of stickers between Bryan and Adam
= (25 u + 5) - 11 u
= 25 u - 11 u + 5
= 14 u + 5
Answer(s): (a) 11 u; (b) 25 u + 5; (c) 36 u + 5; (d) 14 u + 5
