?
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 
and our denominator is 
.
So 
becomes 
.

What is the reciprocal of 
multiplied by the reciprocal of 
?
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 
is 
.
With integers, it helps to remember that all integers are really fractions with a denominator of 
:
, 
, and 
The reciprocals of these numbers are 
and 
respectively.
Therefore, to solve the problem, we first need to find the reciprocals of 
and 
. If we keep in mind that 
, we can determine that the reciprocals are 
and 
, respectively. The product of these two numbers is:
is our final answer.

What is the sum of the reciprocal of 
and 
?
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 
is 
.
Then we need to find the sum of 4 and 7, which is 11.
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.

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.
