Give the answers in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Adam has some money.
Adam spends
13 of his money on some muffins.
He spends
17 of his money on some beads.
- Amount that Adam spends on the muffins = _____ u
- Amount that Adam spends on the beads = _____ u
- Amount that Adam has in the end = _____ u
- Difference in the amounts that he spends on the muffins and the beads = _____ u
(a)
Make the denominators the same.
13 of his money =
721 of his money
17 of his money =
321 of his money
Amount that Adam spends on the muffins = 7 u
(b)
Amount that Adam spends on the beads = 3 u
(c)
Amount that Adam has in the end
= 21 u - 3 u - 7 u
= 11 u
(d)
Difference in the amounts that he spends on the muffins and the beads
= 7 u - 3 u
= 4 u
Answer(s): (a) 7; (b) 3; (c) 11 ; (d) 4
