You are choosing 18 CDs to take to a party.

You want two-thirds of the CDs to have dance music. How many dance music CDs should you choose?

estimating a product
Estimating a Product

You have 15 CDs. Each CD case is three-eighths inch wide. Estimate how wide a space you need on a CD rack to fit all 15 CDs.

Space = x 15

Space = x 16

Space = 6 Think: of 16 is 2, so multiply 2 by 3 for 6.
