When two fractions are not equivalent but are parts of the same whole or unit, there are several ways to find which is greater through comparison. It is important that the fractions refer to the same whole or unit though. This could be comparing a fractional amount of a pizza to a fractional amount of a pizza the same size. Other examples that are possible are to compare length in feet versus length in feet, area in feet squared versus area in feet squared, or comparing weight measured in pounds. However, comparing fractional amounts of two different units can be difficult to do. For example, 1/3 of a cake versus 4/5 of a chocolate bar. 4/5 is a larger number than 1/3 but the cake may actually be bigger in size compared to the remaining chocolate bar.
