Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
711 of the stickers that Bryan has is 7 more than
710 of what Adam has.
Let
710 of Adam's stickers be 7 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.
710 of Adam's stickers → 7 u
110 of Adam's stickers → 1 u
1010 of Adam's stickers → 10 u
Number of Adam's stickers = 10 u
(b)
711 of Bryan's stickers → 7 u + 7
111 of Bryan's stickers → (7 u + 7) ÷ 7 = 1 u + 1
1111 of Bryan's stickers → 11 x (1 u + 1) = 11 u + 11
Number of Bryan's stickers = 11 u + 11
(c)
Total number of stickers
= 10 u + 11 u + 11
= 21 u + 11
(d)
Difference in the number of stickers between Bryan and Adam
= (11 u + 11) - 10 u
= 11 u - 10 u + 11
= 1 u + 11
Answer(s): (a) 10 u; (b) 11 u + 11; (c) 21 u + 11; (d) 1 u + 11
