At a fruit stall, there were 765 lemons and oranges at first.
35 of the lemons and
18 of the oranges were sold. In the end, there were same number of lemons and oranges. How many more lemons than oranges were sold?
| |
Lemons |
Oranges |
| Before |
5x7 =
35 u |
8x2 =
16 u |
| Change |
- 3x7 =
- 21 u
|
- 1x2 =
- 2 u
|
| After |
2x7 =
14 u |
7x2 =
14 u |
Comparing lemons
and oranges in the end |
1x14 =
14 u |
1x14 =
14 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 2, 7 and 1 is 14.
Number of lemons and oranges in the end
= 35 u + 16 u
= 51 u
51 u = 765
1 u = 765 ÷ 51 = 15
Number of more lemons than oranges sold
= 21 u - 2 u
= 19 u
= 19 x 15
= 285
Answer(s): 285
