Justin had peaches and oranges. The ratio of peaches to oranges was 9 : 7. After
45 of the peaches and 136 oranges were sold, there were 9 times as many peaches as oranges left. How many peaches and oranges were sold?
| |
Peaches |
Oranges |
Comparing peaches
and oranges at first |
9x5 =
45 u |
7x5 =
35 u |
| Before |
5x9 =
45 u |
|
| Change |
- 4x9 =
- 36 u |
- 136 |
| After |
1x9 =
9 u |
|
Comparing peaches
and oranges 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 5 is 45.
Number of oranges sold
= 35 u - 1 u
= 34 u
34 u = 136
1 u = 136 ÷ 34 = 4
Number of peaches and oranges sold
= 36 u + 136
= 36 x 4 + 136
= 144 + 136
= 280
Answer(s): 280
