Andy had some apples and starfruits. The number of apples and starfruits left were the same after Andy sold
12 of the apples and
35 of the starfruits. If he had 72 apples at first,
- How many apples were left?
- How many starfruits did Andy have at first?

Before |
2x2 =
4 u |
5 u |
Change |
- 1x2 =
- 2 u |
- 3 u |
After |
1x2 =
2 u |
2 u |
(a)
Fraction of the apples left
= 1 -
12 =
12 Fraction of the starfruits left
= 1 -
35 =
25The number of apples and starfruits left were the same. Make the number of apples and starfruits left the same. LCM of 1 and 2 is 2.
Number of apples at first = 4 u
Number of starfruits at first = 5 u
4 u = 72
1 u = 72 ÷ 4 = 18
Number of apples left
= 2 u
= 2 x 18
= 36
(b)
Number of starfruits at first
= 5 u
= 5 x 18
= 90
Answer(s): (a) 36; (b) 90
