At a fruit stall, there were 728 pomegranates and mangosteens at first.
14 of the pomegranates and
18 of the mangosteens were sold. In the end, there were same number of pomegranates and mangosteens. How many more pomegranates than mangosteens were sold?
| |
Pomegranates |
Mangosteens |
| Before |
4x7 =
28 u |
8x3 =
24 u |
| Change |
- 1x7 =
- 7 u
|
- 1x3 =
- 3 u
|
| After |
3x7 =
21 u |
7x3 =
21 u |
Comparing pomegranates
and mangosteens in the end |
1x21 =
21 u |
1x21 =
21 u |
The number of pomegranates and mangosteens in the end is the same. Make the number of pomegranates and mangosteens in the end the same. LCM of 3, 7 and 1 is 21.
Number of pomegranates and mangosteens in the end
= 28 u + 24 u
= 52 u
52 u = 728
1 u = 728 ÷ 52 = 14
Number of more pomegranates than mangosteens sold
= 7 u - 3 u
= 4 u
= 4 x 14
= 56
Answer(s): 56
