Question

Before making invitations, Katrina counted the supplies she bought for her party.

She counted 36 water balloons and 81 beads to make bracelets.
She then needed to decide how many invitations to make. What is the largest number of friends she can invite so each person gets the same amount of water balloons and each friend gets the same number of beads?

Answer 1

C. 9

Explanation:

9 is the largest number that can fit into both 36 and 81 without a remainder.

Answer 2

The GCF of 36 and 81 is 9

36/9 = 4 water balloons
81/9 = 9 beads

Katrina can invite 9 friends, with each getting 4 water balloons and 9 beads
