Marigolds |
Total |
Before |
9x-2 = -18 u |
10 u
|
-8 u |
Change |
- 1x-2 = - -2 u |
- 9 u |
|
Comparing peonies and marigolds sold |
- -2x1 = - -2 u |
- 9x1 = - 9 u |
- 7x1 = - 7 u |
After |
8x-2 = -16 u |
1 u |
-15 u |
Number of peonies sold is repeated. Make the number of peonies the same. LCM of 1 and -2 is -2.
Total number of flowers sold = 7 u
Total number of flowers
= -18 u + 10 u
= -8 u
Fraction of the flowers that the florist sold
=
7-8 =
-158 Answer(s):
