Before |
2x5 = 10 u |
11 u

Comparing carnations and orchids sold |
- 5x1 = - 5 u |
- 7x1 = - 7 u |
- 12x1 = - 12 u |
After |
1x5 = 5 u |
4 u |
9 u |
Number of carnations sold is repeated. Make the number of carnations the same. LCM of 1 and 5 is 5.

Total number of flowers
= 10 u + 11 u
= 21 u
Fraction of the flowers that the florist sold
