Before |
7x9 = 63 u |
2 u
|
65 u |
Change |
- 1x9 = - 9 u |
- 1 u |
|
Comparing roses and orchids sold |
- 9x1 = - 9 u |
- 1x1 = - 1 u |
- 10x1 = - 10 u |
After |
6x9 = 54 u |
1 u |
55 u |
Number of roses sold is repeated. Make the number of roses the same. LCM of 1 and 9 is 9.
Total number of flowers sold = 10 u
Total number of flowers
= 63 u + 2 u
= 65 u
Fraction of the flowers that the florist sold
=
1065 =
