Before |
7x11 = 77 u |
3 u
|
80 u |
Change |
- 1x11 = - 11 u |
- 1 u |
|
Comparing daffodils and lilies sold |
- 11x1 = - 11 u |
- 1x1 = - 1 u |
- 12x1 = - 12 u |
After |
6x11 = 66 u |
2 u |
68 u |
Number of daffodils sold is repeated. Make the number of daffodils the same. LCM of 1 and 11 is 11.
Total number of flowers sold = 12 u
Total number of flowers
= 77 u + 3 u
= 80 u
Fraction of the flowers that the florist sold
=
1280 =
320 Answer(s):
