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