The rule about negative exponents is that you put the base under "1" in a fraction and the negative exponent becomes positive. For example,
becomes
. So in your case,
The question that can be best modeled as a division expression is how many 3/8's are in 48.
<h3>What is division? </h3>
Division is the process of dividing a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations. The other mathematical operations are addition, multiplication and division.
In order to determine the 3/8's in 48, divide 48 by 3/8.
In order to determine 3/8 of 48, multiply 48 by 3/8.
In order to determine the total of 3/8 and 48, add the numbers together.
In order to determine how much more than 3/8 is 48, subtract 3/8 from 48.

Easy way to get the answer, get your handy calculator and do 387*.75 = 290.25
We conclude that he drove 176 miles on the highway
<h3>how many highway miles did he drive?</h3>
Here we have the equation:
A = (1/18)*c + (1/32)*h
Where A is the consumption in gallons of gas, c is the number of miles driven in the city and h is the number of miles driven in the highway.
Here we know that:
A = 8 gallons of gas.
c = 45 miles
Replacing that in the above equation, we can find the value of h.
8 = (1/18)*45 + (1/32)*h
8 - (1/18)*45 = (1/32)*h
32*(8 - (1/18)*45) = h = 176
We conclude that he drove 176 miles on the highway
