Before |
5x11 = 55 u |
2 u

57 u |
Change |
- 1x11 = - 11 u |
- 1 u |
|
Comparing orchids and roses sold |
- 11x1 = - 11 u |
- 1x1 = - 1 u |
- 12x1 = - 12 u |
After |
4x11 = 44 u |
1 u |
45 u |
Number of orchids sold is repeated. Make the number of orchids the same. LCM of 1 and 11 is 11.

Total number of flowers
= 55 u + 2 u
= 57 u
Fraction of the flowers that the florist sold
