At a fruit stall, there were 312 lemons and pears at first.
35 of the lemons and
27 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 |
5x5 =
25 u |
7x2 =
14 u |
| Change |
- 3x5 =
- 15 u
|
- 2x2 =
- 4 u
|
| After |
2x5 =
10 u |
5x2 =
10 u |
Comparing lemons
and pears in the end |
1x10 =
10 u |
1x10 =
10 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 2, 5 and 1 is 10.
Number of lemons and pears in the end
= 25 u + 14 u
= 39 u
39 u = 312
1 u = 312 ÷ 39 = 8
Number of less pears than lemons were sold
= 15 u - 4 u
= 11 u
= 11 x 8
= 88
Answer(s): 88
