Total |
Before |
6x-2 = -12 u |
10 u
|
-2 u |
Change |
- 1x-2 = - -2 u |
- 9 u |
|
Comparing orchids and tulips sold |
- -2x1 = - -2 u |
- 9x1 = - 9 u |
- 7x1 = - 7 u |
After |
5x-2 = -10 u |
1 u |
-9 u |
Number of orchids sold is repeated. Make the number of orchids the same. LCM of 1 and -2 is -2.
Total number of flowers sold = 7 u
Total number of flowers
= -12 u + 10 u
= -2 u
Fraction of the flowers that the florist sold
=
7-2 =
-92 Answer(s):
-92
