Harry had lemons and kiwis. The ratio of lemons to kiwis was 6 : 5. After
45 of the lemons and 72 kiwis were sold, there were 6 times as many lemons as kiwis left. How many lemons and kiwis were there at first?
| |
Lemons |
Kiwis |
Comparing lemons
and kiwis at first |
6x5 =
30 u |
5x5 =
25 u |
| Before |
5x6 =
30 u |
|
| Change |
- 4x6 =
- 24 u |
- 72 |
| After |
1x6 =
6 u |
|
Comparing lemons
and kiwis in the end |
6 u |
1 u |
The number of lemons at first is repeated. Make the number of lemons at first the same. LCM of 6 and 5 is 30.
Number of kiwis sold
= 25 u - 1 u
= 24 u
24 u = 72
1 u = 72 ÷ 24 = 3
Number of lemons and kiwis at first
= 30 u + 25 u
= 55 u
= 55 x 3
= 165
Answer(s): 165
