Before |
3x11 = 33 u |
7 u

40 u |
Change |
- 1x11 = - 11 u |
- 1 u |
|
Comparing orchids and lilies sold |
- 11x1 = - 11 u |
- 1x1 = - 1 u |
- 12x1 = - 12 u |
After |
2x11 = 22 u |
6 u |
28 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 sold = 12 u
Total number of flowers
= 33 u + 7 u
= 40 u
Fraction of the flowers that the florist sold
=
1240 =
