Marigolds |
Total |
Before |
10x7 = 70 u |
11 u
|
81 u |
Change |
- 1x7 = - 7 u |
- 2 u |
|
Comparing sunflowers and marigolds sold |
- 7x1 = - 7 u |
- 2x1 = - 2 u |
- 9x1 = - 9 u |
After |
9x7 = 63 u |
9 u |
72 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
= 70 u + 11 u
= 81 u
Fraction of the flowers that the florist sold
=
981 =
