At a fruit stall, there were 255 kiwis and starfruits at first.
25 of the kiwis and
17 of the starfruits were sold. In the end, there were same number of kiwis and starfruits. How many less starfruits than kiwis were sold?
| |
Kiwis |
Starfruits |
| Before |
5x2 =
10 u |
7x1 =
7 u |
| Change |
- 2x2 =
- 4 u
|
- 1x1 =
- 1 u
|
| After |
3x2 =
6 u |
6x1 =
6 u |
Comparing kiwis
and starfruits in the end |
1x6 =
6 u |
1x6 =
6 u |
The number of kiwis and starfruits in the end is the same. Make the number of kiwis and starfruits in the end the same. LCM of 3, 6 and 1 is 6.
Number of kiwis and starfruits in the end
= 10 u + 7 u
= 17 u
17 u = 255
1 u = 255 ÷ 17 = 15
Number of less starfruits than kiwis were sold
= 4 u - 1 u
= 3 u
= 3 x 15
= 45
Answer(s): 45
