Jeremy Berger from McDole Elementary explains how to multiply whole numbers by fractions using the repeated addition model. He uses the example of multiplying three by three-fourths, demonstrating how to separate fractions into parts, draw rectangles, and shade sections to represent the fractions. The process involves adding the shaded parts to find the total, resulting in nine-fourths. This method is suitable for fifth-grade math and can be further converted to a mixed number if needed.
