Total |
Before |
10x3 = 30 u |
12 u
|
42 u |
Change |
- 1x3 = - 3 u |
- 7 u |
|
Comparing carnations and marigolds sold |
- 3x1 = - 3 u |
- 7x1 = - 7 u |
- 10x1 = - 10 u |
After |
9x3 = 27 u |
5 u |
32 u |
Number of carnations sold is repeated. Make the number of carnations the same. LCM of 1 and 3 is 3.

Total number of flowers
= 30 u + 12 u
= 42 u
Fraction of the flowers that the florist sold
=
