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