At a fruit stall, there were 722 kiwis and lemons at first.
14 of the kiwis and
16 of the lemons were sold. In the end, there were same number of kiwis and lemons. How many less lemons than kiwis were sold?
| |
Kiwis |
Lemons |
| Before |
4x5 =
20 u |
6x3 =
18 u |
| Change |
- 1x5 =
- 5 u
|
- 1x3 =
- 3 u
|
| After |
3x5 =
15 u |
5x3 =
15 u |
Comparing kiwis
and lemons in the end |
1x15 =
15 u |
1x15 =
15 u |
The number of kiwis and lemons in the end is the same. Make the number of kiwis and lemons in the end the same. LCM of 3, 5 and 1 is 15.
Number of kiwis and lemons in the end
= 20 u + 18 u
= 38 u
38 u = 722
1 u = 722 ÷ 38 = 19
Number of less lemons than kiwis were sold
= 5 u - 3 u
= 2 u
= 2 x 19
= 38
Answer(s): 38
