19 of the lavenders and
14 of the orchids.
910 of the flowers sold were lavenders. What fraction of the flowers did the florist sell?

Lavenders |
Orchids |
Total |
Before |
9x9 = 81 u |
4 u
|
85 u |
Change |
- 1x9 = - 9 u |
- 1 u |
|
Comparing lavenders and orchids sold |
- 9x1 = - 9 u |
- 1x1 = - 1 u |
- 10x1 = - 10 u |
After |
8x9 = 72 u |
3 u |
75 u |
Number of lavenders sold is repeated. Make the number of lavenders the same. LCM of 1 and 9 is 9.
Total number of flowers sold = 10 u
Total number of flowers
= 81 u + 4 u
= 85 u
Fraction of the flowers that the florist sold
=
1085 =
