Multipling Whole Numbers by Fractions

The video tutorial explains how to multiply whole numbers by fractions using three examples. The first example involves running a distance, the second involves biking through city blocks, and the third uses repeated addition to solve a fraction multiplication problem. The key steps are to multiply the whole number by the numerator and then divide by the denominator. The video emphasizes the simplicity and effectiveness of this method.
