Wieners are sold in packages of 12. Hot dog buns are sold in packages of 8. Suppose you plan to sell about 75 hot dogsto raise money for charity. You do not want any wieners or buns left over How many packages of each should you buy?Draw two number lines (showing multiples) of 12 and 8, and find a common multiple close to 75!

Circle the common multiples: 24, 48, 72. Since 72 is close to 75, you should buy 72 wieners and 72 buns. You skip counted by eight 9 times to reach 72, so buy 9 packages of buns. You skip counted by twelve 6 times to reach 72, so buy 6 packages of wieners.
