Explanation
In order to divide a fraction by a second fraction, we can change the problem to a division problem by multiplying the first fraction by the reciprocal of the second fraction. It can be written algebraically in the following way:
Let's use this rule to solve our problem.
Rewrite.
Cross out like terms.

is
of which of the following numbers?
Explanation
In order to solve this problem, we need to understand the relationship between percentages and ratios. Percents can be written as a value over a whole. In this case , our whole is one-hundred percent; therefore, we can write the following:
Now, we need to create a relationship between our known value and the number we need to calculate. In the problem, we know that is
of another number we will name,
. Using this information we need to construct a proportion. We can write the following proportion:
We can cross multiply and solve for the unknown variable.
Rewrite.
Simplify.
Divide both sides of the equation by .
