At a fruit stall, there were 255 kiwis and lemons at first.
25 of the kiwis and
17 of the lemons were sold. In the end, there were same number of kiwis and lemons. How many more kiwis than lemons were sold?
| |
Kiwis |
Lemons |
| Before |
5x2 =
10 u |
7x1 =
7 u |
| Change |
- 2x2 =
- 4 u
|
- 1x1 =
- 1 u
|
| After |
3x2 =
6 u |
6x1 =
6 u |
Comparing kiwis
and lemons in the end |
1x6 =
6 u |
1x6 =
6 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, 6 and 1 is 6.
Number of kiwis and lemons in the end
= 10 u + 7 u
= 17 u
17 u = 255
1 u = 255 ÷ 17 = 15
Number of more kiwis than lemons sold
= 4 u - 1 u
= 3 u
= 3 x 15
= 45
Answer(s): 45
