Bobby had kiwis and apples. The ratio of kiwis to apples was 8 : 7. After
45 of the kiwis and 68 apples were sold, there were 8 times as many kiwis as apples left. How many kiwis and apples were sold?
| |
Kiwis |
Apples |
Comparing kiwis
and apples at first |
8x5 =
40 u |
7x5 =
35 u |
| Before |
5x8 =
40 u |
|
| Change |
- 4x8 =
- 32 u |
- 68 |
| After |
1x8 =
8 u |
|
Comparing kiwis
and apples in the end |
8 u |
1 u |
The number of kiwis at first is repeated. Make the number of kiwis at first the same. LCM of 8 and 5 is 40.
Number of apples sold
= 35 u - 1 u
= 34 u
34 u = 68
1 u = 68 ÷ 34 = 2
Number of kiwis and apples sold
= 32 u + 68
= 32 x 2 + 68
= 64 + 68
= 132
Answer(s): 132
