Fill in the blanks in units (Eg 3 u) or unit equations (Eg 1 u + 2).
Adam and Bryan have some stickers.
310 of the stickers that Adam has is 6 more than
911 of what Bryan has.
Let
911 of Bryan's stickers be 9 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.
911 of Bryan's stickers → 9 u
111 of Bryan's stickers → 1 u
1111 of Bryan's stickers → 11 u
Number of Bryan's stickers = 11 u
(b)
310 of Adam's stickers → 9 u + 6
110 of Adam's stickers → (9 u + 6) ÷ 3 = 3 u + 2
1010 of Adam's stickers → 10 x (3 u + 2) = 30 u + 20
Number of Adam's stickers = 30 u + 20
(c)
Total number of stickers
= 11 u + 30 u + 20
= 41 u + 20
(d)
Difference in the number of stickers between Adam and Bryan
= (30 u + 20) - 11 u
= 30 u - 11 u + 20
= 19 u + 20
Answer(s): (a) 11 u; (b) 30 u + 20; (c) 41 u + 20; (d) 19 u + 20
