Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
511 of the stickers that Bryan has is 10 less than
59 of what Adam has.
Let
59 of Adam's stickers be 5 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.
59 of Adam's stickers → 5 u
19 of Adam's stickers → 1 u
99 of Adam's stickers → 9 u
Number of Adam's stickers = 9 u
(b)
511 of Bryan's stickers → 5 u - 10
111 of Bryan's stickers → 5 u - 10 = (5 u - 10) ÷ 5 = 1 u - 2
1111 of Bryan's stickers → 11 x (1 u - 2) = 11 u - 22
Number of Bryan's stickers = 11 u - 22
(c)
Total number of stickers
= 9 u + 11 u - 22
= 20 u - 22
(d)
Difference in the number of stickers between Bryan and Adam
= (11 u - 22) - 9 u
= 11 u - 9 u - 22
= 2 u - 22
Answer(s): (a) 9 u; (b) 11 u - 22; (c) 20 u - 22 ; (d) 2 u - 22
