Total |
Before |
6x7 = 42 u |
8 u
|
50 u |
Change |
- 1x7 = - 7 u |
- 1 u |
|
Comparing roses and peonies sold |
- 7x1 = - 7 u |
- 1x1 = - 1 u |
- 8x1 = - 8 u |
After |
5x7 = 35 u |
7 u |
42 u |
Number of roses sold is repeated. Make the number of roses the same. LCM of 1 and 7 is 7.
Total number of flowers sold = 8 u
Total number of flowers
= 42 u + 8 u
= 50 u
Fraction of the flowers that the florist sold
=
850 =
425 Answer(s):
