Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
37 of the stickers that Bryan has is 3 more than
911 of what Adam has.
Let
911 of Adam's stickers be 9 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.
911 of Adam's stickers → 9 u
111 of Adam's stickers → 1 u
1111 of Adam's stickers → 11 u
Number of Adam's stickers = 11 u
(b)
37 of Bryan's stickers → 9 u + 3
17 of Bryan's stickers → (9 u + 3) ÷ 3 = 3 u + 1
77 of Bryan's stickers → 7 x (3 u + 1) = 21 u + 7
Number of Bryan's stickers = 21 u + 7
(c)
Total number of stickers
= 11 u + 21 u + 7
= 32 u + 7
(d)
Difference in the number of stickers between Bryan and Adam
= (21 u + 7) - 11 u
= 21 u - 11 u + 7
= 10 u + 7
Answer(s): (a) 11 u; (b) 21 u + 7; (c) 32 u + 7; (d) 10 u + 7
