Answer:
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.
