EXPRESSING ONE QUANTITY AS A FRACTION OF ANOTHER

To express the given quantities as fraction, we have to know about the terms numerator and denominator.

In the fraction x/y

x is numerator and y is denominator

Incase both quantities are not in the same units, we have to convert both into same kind.
