Scale the fraction up or down so that the denominator is 1.
You can rename it, using reciprocals, so that the fraction becomes a whole number. For example, if you have a rate of 2/5 per 1/2, doubling both gives 4/5 per 1 which is a unit rate. Alternatively, you could multiply both numbers by 5/2 (the reciprocal of the first number, 2/5) giving 1 per 5/4.

A rate is a fraction that compares two quantities measured in different units. If the denominator of the fraction is 1 unit, the rate is called a unit rate.

Literacy rate is the percentage of a population that can read and write.
If you have a rate of X of one thing per Y of another, you divide X by Y and then try to rename the resulting fraction so that both X and Y are whole numbers.

Find an equivalent ratio so that the denominator = 1. This may require the numerator to be a fraction.
For people who are not familiar with fractions it is easier to compare them in the form of unit rates.
percentage = 55.56%% rate:= 90/162 * 100%= 0.5556 * 100%= 55.56%

A fraction is a numerical constant. Being a fraction does not alter that. And, as a constant, its rate of change is precisely zero.
