The different kinds of beads that Casey is using to make purses come in packages of
3 and 9. What is the least number of each
kind of bead that Casey can buy to have an
equal number of each of the different kinds
of beads?

Casey can buy 3 packages with 3 beads and one package with 9 beads to have the same number of beads of each kind.

Step-by-step explanation:

Given that:

The beads come in packages of 3 and 9.

To calculate the least number of beads that Casey can have, we will find the least common multiple of both packages.

Package of three = 3, 6, 9, 12, 15

Package of nine = 9, 18, 27, 36

The least common multiple of 3 and 9 is 9.

Hence,

Casey can buy 3 packages with 3 beads and one package with 9 beads to have the same number of beads of each kind.
