Before |
2x8 = 16 u |
5 u
|
21 u |
Change |
- 1x8 = - 8 u |
- 1 u |
|
Comparing orchids and sunflowers sold |
- 8x1 = - 8 u |
- 1x1 = - 1 u |
- 9x1 = - 9 u |
After |
1x8 = 8 u |
4 u |
12 u |
Number of orchids sold is repeated. Make the number of orchids the same. LCM of 1 and 8 is 8.

Total number of flowers
= 16 u + 5 u
= 21 u
Fraction of the flowers that the florist sold
