Orchids |
Total |
Before |
5x8 = 40 u |
2 u
|
42 u |
Change |
- 1x8 = - 8 u |
- 1 u |
|
Comparing marigolds and orchids sold |
- 8x1 = - 8 u |
- 1x1 = - 1 u |
- 9x1 = - 9 u |
After |
4x8 = 32 u |
1 u |
33 u |
Number of marigolds sold is repeated. Make the number of marigolds the same. LCM of 1 and 8 is 8.
Total number of flowers sold = 9 u
Total number of flowers
= 40 u + 2 u
= 42 u
Fraction of the flowers that the florist sold
=
942 =
