Before |
5x7 = 35 u |
11 u
|
46 u |
Change |
- 1x7 = - 7 u |
- 1 u |
|
Comparing carnations and lilies sold |
- 7x1 = - 7 u |
- 1x1 = - 1 u |
- 8x1 = - 8 u |
After |
4x7 = 28 u |
10 u |
38 u |
Number of carnations sold is repeated. Make the number of carnations the same. LCM of 1 and 7 is 7.

Total number of flowers
= 35 u + 11 u
= 46 u
Fraction of the flowers that the florist sold
=
846 =
