Cody had peaches and oranges. The ratio of peaches to oranges was 7 : 4. After
12 of the peaches and 28 oranges were sold, there were 7 times as many peaches as oranges left. How many peaches and oranges were sold?
| |
Peaches |
Oranges |
Comparing peaches
and oranges at first |
7x2 =
14 u |
4x2 =
8 u |
| Before |
2x7 =
14 u |
|
| Change |
- 1x7 =
- 7 u |
- 28 |
| After |
1x7 =
7 u |
|
Comparing peaches
and oranges in the end |
7 u |
1 u |
The number of peaches at first is repeated. Make the number of peaches at first the same. LCM of 7 and 2 is 14.
Number of oranges sold
= 8 u - 1 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Number of peaches and oranges sold
= 7 u + 28
= 7 x 4 + 28
= 28 + 28
= 56
Answer(s): 56
