To compare two fractions, you must find the GCF. As an example, if you were comparing 1/2 and 2, it can be turned into a fraction because 2 is the same as 2/1. Hope this answers your question. Let me know if you need more help.
They compare because the numerator is like part of a whole the denominator is the whole the dividend is the whole number and the divisor is the partial
The numerator of a fraction is like the dividend in a division expression as both represent what is being divided. The denominator corresponds to the divisor, indicating into how many parts the numerator is divided. Thus, a fraction can be seen as a way to express a division operation.
