Answer:
She can make 12 arrangements.
Explanation:
The question is asking for the GCF, which is 12.
The reason it's asking for the GCF is because you're trying to make equal arrangements with the enough of each flower so that all of them are used, so you need to have the highest number of arrangements possible for each flower that is still usable for the other flowers.
If you look at the number of arrangements as factors, then you're simply looking for the GCF.
12 * 3 = 36
12 * 5 = 60
12 * 6 = 72
Each Arrangement Will Consist of:
3 Carnations, 5 Roses, and 6 Daisies.
