Luis had peaches and kiwis. The ratio of peaches to kiwis was 8 : 5. After
34 of the peaches and 20 kiwis were sold, there were 2 times as many peaches as kiwis left. How many peaches and kiwis were there at first?
| |
Peaches |
Kiwis |
Comparing peaches
and kiwis at first |
8x1 =
8 u |
5x1 =
5 u |
| Before |
4x2 =
8 u |
|
| Change |
- 3x2 =
- 6 u |
- 20 |
| After |
1x2 =
2 u |
|
Comparing peaches
and kiwis in the end |
2 u |
1 u |
The number of peaches at first is repeated. Make the number of peaches at first the same. LCM of 8 and 4 is 8.
Number of kiwis sold
= 5 u - 1 u
= 4 u
4 u = 20
1 u = 20 ÷ 4 = 5
Number of peaches and kiwis at first
= 8 u + 5 u
= 13 u
= 13 x 5
= 65
Answer(s): 65
