At a fruit stall, there were 767 lemons and pears at first.
25 of the lemons and
18 of the pears were sold. In the end, there were same number of lemons and pears. How many less pears than lemons were sold?
|
Lemons |
Pears |
Before |
5x7 = 35 u |
8x3 = 24 u |
Change |
- 2x7 = - 14 u
|
- 1x3 = - 3 u
|
After |
3x7 = 21 u |
7x3 = 21 u |
Comparing lemons and pears in the end |
1x21 = 21 u |
1x21 = 21 u |
The number of lemons and pears in the end is the same. Make the number of lemons and pears in the end the same. LCM of 3, 7 and 1 is 21.
Number of lemons and pears in the end
= 35 u + 24 u
= 59 u
59 u = 767
1 u = 767 ÷ 59 = 13
Number of less pears than lemons were sold
= 14 u - 3 u
= 11 u
= 11 x 13
= 143
Answer(s): 143
