Total |
Before |
5x7 = 35 u |
7 u
|
42 u |
Change |
- 1x7 = - 7 u |
- 1 u |
|
Comparing lilies and peonies sold |
- 7x1 = - 7 u |
- 1x1 = - 1 u |
- 8x1 = - 8 u |
After |
4x7 = 28 u |
6 u |
34 u |
Number of lilies sold is repeated. Make the number of lilies the same. LCM of 1 and 7 is 7.
Total number of flowers sold = 8 u
Total number of flowers
= 35 u + 7 u
= 42 u
Fraction of the flowers that the florist sold
=
842 =
