Understanding Multiplying Fractions

This video tutorial explains how to multiply fractions using models and shortcuts. It begins with a visual representation of multiplying 1/4 by 2/3, showing how to partition a whole into parts. The tutorial then introduces a shortcut for multiplying fractions by multiplying numerators and denominators directly. An example problem, 3/5 times 2/4, is solved using both the model and the shortcut. The video concludes by discussing equivalent fractions and simplifying the result to find the correct answer.

What are the factors in the example of multiplying fractions discussed in the video?

• Two-thirds and three-fifths

• One-fourth and two-thirds

• Two-fifths and three-fourths

• One-half and three-fourths
