Question

Emma has 18 yellow flowers and 30 white flowers. She wants to split them into vases in equal groups. What is the largest number of groups she can make?

Answer 1

6 groups

Explanation:

we need to find the greatest common factor (GCF) of 18 and 30. so lets list all their factors:

18: 1, 2, 3, 6, 9, 18

30: 1, 2, 3, 5, 6, 10, 15, 30

their GCF is 6, so she can make 6 groups. each one will have 3 yellow flowers and 5 white ones.
