Sam is buying packages with 9 beeds each. His mom bought his 63 more beeds. He now has 153 beeds. How many did he buy.

Answer 1

Let's start by finding out how many beads Sam's mom bought for him. We do this by performing 153 - 63 = <<153-63=90>>90 beads.
We know that 9 beads make a package. So, 90 / 9 = <<90/9=10>>10 packages of beads was bought by Sam.
Thus, Sam had to buy 10 packages of beads. Answer: \boxed{10}.
