At the end of this lesson, students should be able to find whole numbers or quantities when given their fractional parts.

NOTE:

In this lesson, we will learn how to find the whole number from which a given fractional part was derived.

This is like a reverse operation of the method used in finding fractional parts.

When finding the whole number from a given fractional part, you multiply the given fractional part by the denominator of the fraction and divide your result by the numerator of the fraction.
