At a fruit stall, there were 944 persimmons and kiwis at first.
25 of the persimmons and
18 of the kiwis were sold. In the end, there were same number of persimmons and kiwis. How many more persimmons than kiwis were sold?
|
Persimmons |
Kiwis |
Before |
5x7 = 35 u |
8x3 = 24 u |
Change |
- 2x7 = - 14 u
|
- 1x3 = - 3 u
|
After |
3x7 = 21 u |
7x3 = 21 u |
Comparing persimmons and kiwis in the end |
1x21 = 21 u |
1x21 = 21 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 3, 7 and 1 is 21.
Number of persimmons and kiwis in the end
= 35 u + 24 u
= 59 u
59 u = 944
1 u = 944 ÷ 59 = 16
Number of more persimmons than kiwis sold
= 14 u - 3 u
= 11 u
= 11 x 16
= 176
Answer(s): 176
