Before |
2x7 = 14 u |
7 u
|
21 u |
Change |
- 1x7 = - 7 u |
- 2 u |
|
Comparing orchids and roses sold |
- 7x1 = - 7 u |
- 2x1 = - 2 u |
- 9x1 = - 9 u |
After |
1x7 = 7 u |
5 u |
12 u |
Number of orchids sold is repeated. Make the number of orchids the same. LCM of 1 and 7 is 7.
Total number of flowers sold = 9 u
Total number of flowers
= 14 u + 7 u
= 21 u
Fraction of the flowers that the florist sold
=
921 =
