At a fruit stall, there were 702 persimmons and kiwis at first.
35 of the persimmons and
27 of the kiwis were sold. In the end, there were same number of persimmons and kiwis. How many less kiwis than persimmons were sold?
|
Persimmons |
Kiwis |
Before |
5x5 = 25 u |
7x2 = 14 u |
Change |
- 3x5 = - 15 u
|
- 2x2 = - 4 u
|
After |
2x5 = 10 u |
5x2 = 10 u |
Comparing persimmons and kiwis in the end |
1x10 = 10 u |
1x10 = 10 u |
The number of persimmons and kiwis in the end is the same. Make the number of persimmons and kiwis in the end the same. LCM of 2, 5 and 1 is 10.
Number of persimmons and kiwis in the end
= 25 u + 14 u
= 39 u
39 u = 702
1 u = 702 ÷ 39 = 18
Number of less kiwis than persimmons were sold
= 15 u - 4 u
= 11 u
= 11 x 18
= 198
Answer(s): 198
