At a fruit stall, there were 418 lemons and oranges at first.
14 of the lemons and
16 of the oranges were sold. In the end, there were same number of lemons and oranges. How many less oranges than lemons were sold?
| |
Lemons |
Oranges |
| Before |
4x5 =
20 u |
6x3 =
18 u |
| Change |
- 1x5 =
- 5 u
|
- 1x3 =
- 3 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing lemons
and oranges in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of lemons and oranges in the end is the same. Make the number of lemons and oranges in the end the same. LCM of 3, 5 and 1 is 15.
Number of lemons and oranges in the end
= 20 u + 18 u
= 38 u
38 u = 418
1 u = 418 ÷ 38 = 11
Number of less oranges than lemons were sold
= 5 u - 3 u
= 2 u
= 2 x 11
= 22
Answer(s): 22
