Comparing dragonfruits
and passion fruits at first |
6x2 =
12 u |
5x2 =
10 u |
| Before |
4x3 =
12 u |
|
| Change |
- 3x3 =
- 9 u |
- 45 |
| After |
1x3 =
3 u |
|
Comparing dragonfruits
and passion fruits in the end |
3 u |
1 u |
The number of dragonfruits at first is repeated. Make the number of dragonfruits at first the same. LCM of 6 and 4 is 12.
Number of passion fruits sold
= 10 u - 1 u
= 9 u
9 u = 45
1 u = 45 ÷ 9 = 5
Number of dragonfruits and passion fruits sold
= 9 u + 45
= 9 x 5 + 45
= 45 + 45
= 90
Answer(s): 90
