At a fruit stall, there were 728 oranges and kiwis at first.
14 of the oranges and
18 of the kiwis were sold. In the end, there were same number of oranges and kiwis. How many less kiwis than oranges were sold?
| |
Oranges |
Kiwis |
| Before |
4x7 =
28 u |
8x3 =
24 u |
| Change |
- 1x7 =
- 7 u
|
- 1x3 =
- 3 u
|
| After |
3x7 =
21 u |
7x3 =
21 u |
Comparing oranges
and kiwis in the end |
1x21 =
21 u |
1x21 =
21 u |
The number of oranges and kiwis in the end is the same. Make the number of oranges and kiwis in the end the same. LCM of 3, 7 and 1 is 21.
Number of oranges and kiwis in the end
= 28 u + 24 u
= 52 u
52 u = 728
1 u = 728 ÷ 52 = 14
Number of less kiwis than oranges were sold
= 7 u - 3 u
= 4 u
= 4 x 14
= 56
Answer(s): 56
