Before |
3x7 = 21 u |
11 u
|
32 u |
Change |
- 1x7 = - 7 u |
- 5 u |
|
Comparing marigolds and sunflowers sold |
- 7x1 = - 7 u |
- 5x1 = - 5 u |
- 12x1 = - 12 u |
After |
2x7 = 14 u |
6 u |
20 u |
Number of marigolds sold is repeated. Make the number of marigolds the same. LCM of 1 and 7 is 7.
Total number of flowers sold = 12 u
Total number of flowers
= 21 u + 11 u
= 32 u
Fraction of the flowers that the florist sold
