The amount of effort saved when using machines is called mechanical advantage (MA). Simple machines use mechanical advantage as a key property to their functionality, helping humans perform tasks that would require more force than a person could produce. We will use the lever as an example of a simple machine to illustrate the concept of mechanical advantage.

Fraction comparison with lowest common denominators.

This video explains how to order fractions by their size.

In this unit we will learn how these factors can affect the output of a simple machine. We will also learn about the difference between ideal mechanical advantage (IMA) and actual mechanical advantage (AMA), and how to apply your knowledge to calculate the efficiency of various simple machines.

In this online lesson you will learn how to compare measurements that have different units.

In this unit you will learn how to convert between common metric units of measure.

YouTube video that explains how to use prime factorization to find the highest common factor and lowest common multiple. It is very simple using the method described in the video.

By the end of this unit you will be able to:

• Use a ruler and protractor accurately
• Understand the SI system of measurement
• Convert between different units
