At a fruit stall, there were 170 persimmons and pomegranates at first.
25 of the persimmons and
17 of the pomegranates were sold. In the end, there were same number of persimmons and pomegranates. How many less pomegranates than persimmons were sold?
| |
Persimmons |
Pomegranates |
| Before |
5x2 =
10 u |
7x1 =
7 u |
| Change |
- 2x2 =
- 4 u
|
- 1x1 =
- 1 u
|
| After |
3x2 =
6 u |
6x1 =
6 u |
Comparing persimmons
and pomegranates in the end |
1x6 =
6 u |
1x6 =
6 u |
The number of persimmons and pomegranates in the end is the same. Make the number of persimmons and pomegranates in the end the same. LCM of 3, 6 and 1 is 6.
Number of persimmons and pomegranates in the end
= 10 u + 7 u
= 17 u
17 u = 170
1 u = 170 ÷ 17 = 10
Number of less pomegranates than persimmons were sold
= 4 u - 1 u
= 3 u
= 3 x 10
= 30
Answer(s): 30
