Albert had persimmons and kiwis. The ratio of persimmons to kiwis was 3 : 2. After
45 of the persimmons and 72 kiwis were sold, there were 3 times as many persimmons as kiwis left. How many persimmons and kiwis were sold?
| |
Persimmons |
Kiwis |
Comparing persimmons
and kiwis at first |
3x5 =
15 u |
2x5 =
10 u |
| Before |
5x3 =
15 u |
|
| Change |
- 4x3 =
- 12 u |
- 72 |
| After |
1x3 =
3 u |
|
Comparing persimmons
and kiwis in the end |
3 u |
1 u |
The number of persimmons at first is repeated. Make the number of persimmons at first the same. LCM of 3 and 5 is 15.
Number of kiwis sold
= 10 u - 1 u
= 9 u
9 u = 72
1 u = 72 ÷ 9 = 8
Number of persimmons and kiwis sold
= 12 u + 72
= 12 x 8 + 72
= 96 + 72
= 168
Answer(s): 168
