Before |
2x5 = 10 u |
8 u

18 u |
Change |
- 1x5 = - 5 u |
- 7 u |
|
Comparing tulips and marigolds sold |
- 5x1 = - 5 u |
- 7x1 = - 7 u |
- 12x1 = - 12 u |
After |
1x5 = 5 u |
1 u |
6 u |
Number of tulips sold is repeated. Make the number of tulips the same. LCM of 1 and 5 is 5.

Total number of flowers
= 10 u + 8 u
= 18 u
Fraction of the flowers that the florist sold
