Total |
Before |
10x7 = 70 u |
2 u
|
72 u |
Change |
- 1x7 = - 7 u |
- 1 u |
|
Comparing daisies and lavenders sold |
- 7x1 = - 7 u |
- 1x1 = - 1 u |
- 8x1 = - 8 u |
After |
9x7 = 63 u |
1 u |
64 u |
Number of daisies sold is repeated. Make the number of daisies the same. LCM of 1 and 7 is 7.
Total number of flowers sold = 8 u
Total number of flowers
= 70 u + 2 u
= 72 u
Fraction of the flowers that the florist sold
=
872 =
