3x11 = 33 u |
9 u

42 u |
Change |
- 1x11 = - 11 u |
- 1 u |
|
Comparing lilies and daisies sold |
- 11x1 = - 11 u |
- 1x1 = - 1 u |
- 12x1 = - 12 u |
After |
2x11 = 22 u |
8 u |
30 u |
Number of lilies sold is repeated. Make the number of lilies the same. LCM of 1 and 11 is 11.

Total number of flowers
= 33 u + 9 u
= 42 u
Fraction of the flowers that the florist sold
=
1242 =
