This is a GCF problem, find the GCF of 36 and 27. To do this, list out the factors for each number. EX 36- 1×36, 2×18, so on and so on. Then do this for 27. The GCF will be the greatest factor. In this case, that is 9. So there would be 9 groups because that is the greatest common factor. there would be 4 roses in each group because 4×9= 36. There are 3 carnations in each group because 9×3 =27. So 9 groups with 4 roses and 3 carnations.
