They usually have a denominator of 1 although numerators of 1 are also possible.
What is a fraction in which the numerator and denominator represent the same amount but are in different units?
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.
It is a ratio.
Proportion
Probably a conversion rate.
In a fraction they must be in the same units. In a ratio they need not be.
A fraction that compares two quantities measured in different units. i know this is the correct answer
A unit conversion ratio
This could be any fraction where the denominator and the numerator are different. For example, 1/2, 3/7, 15/8......and so on. In algebraic terms this would be written x/y where x ≠ y
A conversion factor is a fraction that is always equal to 1. This allows you to convert between different units by multiplying the quantity you have by the conversion factor.
It is the denominator
Nothing happens to the fraction.
