Before |
8x11 = 88 u |
2 u
|
90 u |
Change |
- 1x11 = - 11 u |
- 1 u |
|
Comparing roses and tulips sold |
- 11x1 = - 11 u |
- 1x1 = - 1 u |
- 12x1 = - 12 u |
After |
7x11 = 77 u |
1 u |
78 u |
Number of roses sold is repeated. Make the number of roses the same. LCM of 1 and 11 is 11.

Total number of flowers
= 88 u + 2 u
= 90 u
Fraction of the flowers that the florist sold
=
1290 =
