Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
311 of the stickers that Adam has is 6 less than
35 of what Bryan has.
Let
35 of Bryan's stickers be 3 u.
- Number of stickers that Bryan has = ___________
- Number of stickers that Adam has = ___________
- Total number of stickers = ___________
- Difference in the number of stickers between Adam and Bryan = ___________
(a)
Change fraction into units.
35 of Bryan's stickers → 3 u
15 of Bryan's stickers → 1 u
55 of Bryan's stickers → 5 u
Number of Bryan's stickers = 5 u
(b)
311 of Adam's stickers → 3 u - 6
111 of Adam's stickers → 3 u - 6 = (3 u - 6) ÷ 3 = 1 u - 2
1111 of Adam's stickers → 11 x (1 u - 2) = 11 u - 22
Number of Adam's stickers = 11 u - 22
(c)
Total number of stickers
= 5 u + 11 u - 22
= 16 u - 22
(d)
Difference in the number of stickers between Adam and Bryan
= (11 u - 22) - 5 u
= 11 u - 5 u - 22
= 6 u - 22
Answer(s): (a) 5 u; (b) 11 u - 22; (c) 16 u - 22 ; (d) 6 u - 22
