79 of the carnations.
310 of the flowers sold were marigolds. What fraction of the flowers did the florist sell?

Marigolds |
Carnations |
Total |
Before |
2x3 = 6 u |
9 u
|
15 u |
Change |
- 1x3 = - 3 u |
- 7 u |
|
Comparing marigolds and carnations sold |
- 3x1 = - 3 u |
- 7x1 = - 7 u |
- 10x1 = - 10 u |
After |
1x3 = 3 u |
2 u |
5 u |
Number of marigolds sold is repeated. Make the number of marigolds the same. LCM of 1 and 3 is 3.
Total number of flowers sold = 10 u
Total number of flowers
= 6 u + 9 u
= 15 u
Fraction of the flowers that the florist sold
=
