At a fruit stall, there were 102 oranges and pomegranates at first.
25 of the oranges and
17 of the pomegranates were sold. In the end, there were same number of oranges and pomegranates. How many less pomegranates than oranges were sold?
| |
Oranges |
Pomegranates |
| Before |
5x2 =
10 u |
7x1 =
7 u |
| Change |
- 2x2 =
- 4 u
|
- 1x1 =
- 1 u
|
| After |
3x2 =
6 u |
6x1 =
6 u |
Comparing oranges
and pomegranates in the end |
1x6 =
6 u |
1x6 =
6 u |
The number of oranges and pomegranates in the end is the same. Make the number of oranges and pomegranates in the end the same. LCM of 3, 6 and 1 is 6.
Number of oranges and pomegranates in the end
= 10 u + 7 u
= 17 u
17 u = 102
1 u = 102 ÷ 17 = 6
Number of less pomegranates than oranges were sold
= 4 u - 1 u
= 3 u
= 3 x 6
= 18
Answer(s): 18
