1. The least common denominator of 8 and 12 is 24. 8x3=24 so you would multiply 5 by 3 as well. Since 12x2=24 multiply the 9 by 2.

2. Least common denominator is 30. Multiply the first fraction by 5 and the second one by 2

3. Least common denominator is 42. First fraction is multiplied by 7, and the second one is multiplied by 3.

seraphim [82]

Answer:

The shopper should but the 6 pcs pack because its cheaper.

Step-by-step explanation:

6-pcs pack = $2.10

hot dogs needed = 48

number of 6 pcs = 48 divided 6 = 8

total cost = $2.10 x 6 = $16.80

8 pcs pack = $3.12

hot dogs needed = 48

number of 8 pcs packs = 48 divided 8= 6

total cost = $3.12 x 6 =$18.72
