Give the answers in units (Eg 1 u) or unit equations (Eg 1 u + 2).
Adam has some money.
Adam spends
12 of his money on some muffins.
He spends
15 of his money on some marbles.
- Amount that Adam spends on the muffins = _____ u
- Amount that Adam spends on the marbles = _____ u
- Amount that Adam has in the end = _____ u
- Difference in the amounts that he spends on the muffins and the marbles = _____ u
(a)
Make the denominators the same.
12 of his money =
510 of his money
15 of his money =
210 of his money
Amount that Adam spends on the muffins = 5 u
(b)
Amount that Adam spends on the marbles = 2 u
(c)
Amount that Adam has in the end
= 10 u - 2 u - 5 u
= 3 u
(d)
Difference in the amounts that he spends on the muffins and the marbles
= 5 u - 2 u
= 3 u
Answer(s): (a) 5; (b) 2; (c) 3 ; (d) 3
