At a fruit stall, there were 612 apples and persimmons at first.
35 of the apples and
18 of the persimmons were sold. In the end, there were same number of apples and persimmons. How many less persimmons than apples were sold?
| |
Apples |
Persimmons |
| Before |
5x7 =
35 u |
8x2 =
16 u |
| Change |
- 3x7 =
- 21 u
|
- 1x2 =
- 2 u
|
| After |
2x7 =
14 u |
7x2 =
14 u |
Comparing apples
and persimmons in the end |
1x14 =
14 u |
1x14 =
14 u |
The number of apples and persimmons in the end is the same. Make the number of apples and persimmons in the end the same. LCM of 2, 7 and 1 is 14.
Number of apples and persimmons in the end
= 35 u + 16 u
= 51 u
51 u = 612
1 u = 612 ÷ 51 = 12
Number of less persimmons than apples were sold
= 21 u - 2 u
= 19 u
= 19 x 12
= 228
Answer(s): 228
