Example Questions
Example Question #1 : Reciprocals
What is the reciprocal of 
To get the reciprocal of a fraction, you simply switch the numerator and the denominator.
In our case our numerator is 
So 
Example Question #2 : Reciprocals
Compute:
We will need to rewrite this in order to eliminate the negative exponent in the problem.
Because the denominator has a negative exponent, that is the same as having a positive exponent in the numerator. Therefore we can rewrite the problem as follows and then multiply.
Example Question #2 : Manipulation Of Fractions
Evaluate:
To divide a term by a fraction, take the reciprocal of the fraction.
Then mutiply both terms.
Example Question #3 : Reciprocals
What is the sum of the reciprocal of 
To find the reciprocal of a fraction, flip the numerator and the denominator.
Thus, the reciprocal of 
Then we need to find the sum of 4 and 7, which is 11.
Example Question #53 : Fractions
What is the reciprocal of 
To find the reciprocal of a fraction, we simply need to switch the numerator and the denominator: for example, the reciprocal of a fraction 
With integers, it helps to remember that all integers are really fractions with a denominator of 
The reciprocals of these numbers are 
Therefore, to solve the problem, we first need to find the reciprocals of
