What is a fraction in which the numerator and denominator represent the same amount but are in different units?
It is a ratio.
A unit conversion ratio
In a fraction they must be in the same units. In a ratio they need not be.
Multiply it by a fraction that has a certain number of inches in the numerator and the same length as the numerator but in the units of the given height in the denominator. The original units cancel out, and you're left with inches. If the numerator and denominator of a fraction are equal, the fraction is equal to 1, and multiplying something by 1 does not change its value.

They usually have a denominator of 1 although numerators of 1 are also possible.

There are three main ways to express a fraction: as a fraction, and improper number, or as a decimal. A fraction follows the syntax a/b where b is the units (halfs, quarters, twenty-thirds) being expressed and a is the number of units that the fraction represents. An improper fraction can be created when the numerator is greater than the denominator, allowing us to take the value of the denominator out of the numerator allowing us to bring the number of times we were able to remove the denominator from the numerator outside the fraction (e.i. 5/4 = 1 1/4 or 9/4 = 2 1/4). A decimal expression of a fraction can be created by simply dividing the numerator of the fraction by the denominator (i.e. 2/3 = 0.667).
Write the conversion as a fraction. Then multiply the numerator and denominator across, then cancel any units that are both top and bottom.
The numerator tells you how many of the denominator units you have.

I had to find this out for chemisty...an d i couldn't find the answer but i did find "a conversion factor is a fraction whose numerator and denominator are the same quantity expressed in different units." This may help but idk. If you have a white chemistry book with a yellow triangle then its on page 25.Hope this helps! ☺
