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 4 more than
411 of what Adam has.
Let
411 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.
411 of Adam's stickers → 4 u
111 of Adam's stickers → 1 u
1111 of Adam's stickers → 11 u
Number of Adam's stickers = 11 u
(b)
211 of Bryan's stickers → 4 u + 4
111 of Bryan's stickers → (4 u + 4) ÷ 2 = 2 u + 2
1111 of Bryan's stickers → 11 x (2 u + 2) = 22 u + 22
Number of Bryan's stickers = 22 u + 22
(c)
Total number of stickers
= 11 u + 22 u + 22
= 33 u + 22
(d)
Difference in the number of stickers between Bryan and Adam
= (22 u + 22) - 11 u
= 22 u - 11 u + 22
= 11 u + 22
Answer(s): (a) 11 u; (b) 22 u + 22; (c) 33 u + 22; (d) 11 u + 22
