Answer:
Option B: (½•16)⅓
Step-by-step explanation:
The associative property states that we can add or multiply numbers in a group regardless of how those numbers are grouped. And that we will get the same answer.
For example;
x(y•z) = (x•y)z = (x•z)y
Now in our question, we want o evaluate; ½(16•⅓)
Using the associative property, the best expression will be: (½•16)⅓
It's the best expression because the terms in the bracket are easy to multiply out without remainder.
Thus, option B is correct

The minivan travels more miles per gallon
Step-by-step explanation:
To determine the unit rate, take the miles and divide by the gallons
Truck:
120 miles / 8 gallons =15 miles per gallon
Minivan:
180 miles /10 gallons = 18 miles per gallon
The minivan travels more miles per gallon
keeping in mind that there are 12 months in a year, thus 18 months is really 18/12 years.
