Bobby had starfruits and kiwis. The ratio of starfruits to kiwis was 6 : 5. After
12 of the starfruits and 16 kiwis were sold, there were 3 times as many starfruits as kiwis left. How many starfruits and kiwis were sold?
| |
Starfruits |
Kiwis |
Comparing starfruits
and kiwis at first |
6x1 =
6 u |
5x1 =
5 u |
| Before |
2x3 =
6 u |
|
| Change |
- 1x3 =
- 3 u |
- 16 |
| After |
1x3 =
3 u |
|
Comparing starfruits
and kiwis in the end |
3 u |
1 u |
The number of starfruits at first is repeated. Make the number of starfruits at first the same. LCM of 6 and 2 is 6.
Number of kiwis sold
= 5 u - 1 u
= 4 u
4 u = 16
1 u = 16 ÷ 4 = 4
Number of starfruits and kiwis sold
= 3 u + 16
= 3 x 4 + 16
= 12 + 16
= 28
Answer(s): 28
