The lowest common denominator is defined as the set of fraction denominators with the lowest common multiple. The lowest positive integer with more than one denominator in the set is LCD.
Given that the Peanuts are sold in 8-ounce and 12-ounce packages
We have to determine the number of ounces you can buy from each package to have equal amounts of each package size
8 = 2 × 2 × 2
12 = 2 × 2 × 3
The LCDs 8 and 12 are 24
Thus, three 8 oz packets and two 12 oz packets.
Therefore, you can buy from each package to have equal amounts of each package size the number o ounces as 3 packets of 8 ounces and 2 packets of 12 ounces.
