Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Bryan and Adam have some stickers.
310 of the stickers that Bryan has is 3 less than
35 of what Adam has.
Let
35 of Adam's stickers be 3 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.
35 of Adam's stickers → 3 u
15 of Adam's stickers → 1 u
55 of Adam's stickers → 5 u
Number of Adam's stickers = 5 u
(b)
310 of Bryan's stickers → 3 u - 3
110 of Bryan's stickers → 3 u - 3 = (3 u - 3) ÷ 3 = 1 u - 1
1010 of Bryan's stickers → 10 x (1 u - 1) = 10 u - 10
Number of Bryan's stickers = 10 u - 10
(c)
Total number of stickers
= 5 u + 10 u - 10
= 15 u - 10
(d)
Difference in the number of stickers between Bryan and Adam
= (10 u - 10) - 5 u
= 10 u - 5 u - 10
= 5 u - 10
Answer(s): (a) 5 u; (b) 10 u - 10; (c) 15 u - 10 ; (d) 5 u - 10
