At a fruit stall, there were 646 oranges and lemons at first.
14 of the oranges and
16 of the lemons were sold. In the end, there were same number of oranges and lemons. How many more oranges than lemons were sold?
| |
Oranges |
Lemons |
| Before |
4x5 =
20 u |
6x3 =
18 u |
| Change |
- 1x5 =
- 5 u
|
- 1x3 =
- 3 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing oranges
and lemons in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of oranges and lemons in the end is the same. Make the number of oranges and lemons in the end the same. LCM of 3, 5 and 1 is 15.
Number of oranges and lemons in the end
= 20 u + 18 u
= 38 u
38 u = 646
1 u = 646 ÷ 38 = 17
Number of more oranges than lemons sold
= 5 u - 3 u
= 2 u
= 2 x 17
= 34
Answer(s): 34
