At a fruit stall, there were 153 starfruits and pears at first.
35 of the starfruits and
37 of the pears were sold. In the end, there were same number of starfruits and pears. How many more starfruits than pears were sold?
|
Starfruits |
Pears |
Before |
5x2 = 10 u |
7x1 = 7 u |
Change |
- 3x2 = - 6 u
|
- 3x1 = - 3 u
|
After |
2x2 = 4 u |
4x1 = 4 u |
Comparing starfruits and pears in the end |
1x4 = 4 u |
1x4 = 4 u |
The number of starfruits and pears in the end is the same. Make the number of starfruits and pears in the end the same. LCM of 2, 4 and 1 is 4.
Number of starfruits and pears in the end
= 10 u + 7 u
= 17 u
17 u = 153
1 u = 153 ÷ 17 = 9
Number of more starfruits than pears sold
= 6 u - 3 u
= 3 u
= 3 x 9
= 27
Answer(s): 27
