Before |
3x7 = 21 u |
9 u
|
30 u |
Change |
- 1x7 = - 7 u |
- 2 u |
|
Comparing sunflowers and orchids sold |
- 7x1 = - 7 u |
- 2x1 = - 2 u |
- 9x1 = - 9 u |
After |
2x7 = 14 u |
7 u |
21 u |
Number of sunflowers sold is repeated. Make the number of sunflowers the same. LCM of 1 and 7 is 7.
Total number of flowers sold = 9 u
Total number of flowers
= 21 u + 9 u
= 30 u
Fraction of the flowers that the florist sold
=
930 =
