Caden had kiwis and oranges. The ratio of kiwis to oranges was 3 : 2. After
25 of the kiwis and 54 oranges were sold, there were 9 times as many kiwis as oranges left. How many kiwis and oranges were sold?
| |
Kiwis |
Oranges |
Comparing kiwis
and oranges at first |
3x5 =
15 u |
2x5 =
10 u |
| Before |
5x3 =
15 u |
|
| Change |
- 2x3 =
- 6 u |
- 54 |
| After |
3x3 =
9 u |
|
Comparing kiwis
and oranges in the end |
9 u |
1 u |
The number of kiwis at first is repeated. Make the number of kiwis at first the same. LCM of 3 and 5 is 15.
Number of oranges sold
= 10 u - 1 u
= 9 u
9 u = 54
1 u = 54 ÷ 9 = 6
Number of kiwis and oranges sold
= 6 u + 54
= 6 x 6 + 54
= 36 + 54
= 90
Answer(s): 90
