Albert had peaches and apples. The ratio of peaches to apples was 9 : 8. After
12 of the peaches and 135 apples were sold, there were 9 times as many peaches as apples left. How many peaches and apples were there at first?
|
Peaches |
Apples |
Comparing peaches and apples at first |
9x2 = 18 u |
8x2 = 16 u |
Before |
2x9 = 18 u |
|
Change |
- 1x9 = - 9 u |
- 135 |
After |
1x9 = 9 u |
|
Comparing peaches and apples in the end |
9 u |
1 u |
The number of peaches at first is repeated. Make the number of peaches at first the same. LCM of 9 and 2 is 18.
Number of apples sold
= 16 u - 1 u
= 15 u
15 u = 135
1 u = 135 ÷ 15 = 9
Number of peaches and apples at first
= 18 u + 16 u
= 34 u
= 34 x 9
= 306
Answer(s): 306
