At a fruit stall, there were 352 starfruits and oranges at first.
35 of the starfruits and
17 of the oranges were sold. In the end, there were same number of starfruits and oranges. How many more starfruits than oranges were sold?
| |
Starfruits |
Oranges |
| Before |
5x3 =
15 u |
7x1 =
7 u |
| Change |
- 3x3 =
- 9 u
|
- 1x1 =
- 1 u
|
| After |
2x3 =
6 u |
6x1 =
6 u |
Comparing starfruits
and oranges in the end |
1x6 =
6 u |
1x6 =
6 u |
The number of starfruits and oranges in the end is the same. Make the number of starfruits and oranges in the end the same. LCM of 2, 6 and 1 is 6.
Number of starfruits and oranges in the end
= 15 u + 7 u
= 22 u
22 u = 352
1 u = 352 ÷ 22 = 16
Number of more starfruits than oranges sold
= 9 u - 1 u
= 8 u
= 8 x 16
= 128
Answer(s): 128
