## Understanding Equations

Required Resource-Read/review the following resources for this activity:

• Textbook (Pre-Algebra): Chapter 2, 3, 4, 8
• Minimum of 1 outside scholarly source (in addition to the textbook)

Instructions-Being successful in mathematics requires understanding as opposed to simple memorization. For example, the formula to find the perimeter of a rectangle is P = 2L + 2W (where L is length and W is width). Memorizing the formula could be helpful, but, if we understand that the perimeter is the distance around the rectangle, we are able to construct the formula and apply it to real-world situations correctly.

For the initial post, find another formula that you use in your daily life, and explain the meaning behind it.

For example, the formula to calculate sales tax on a purchase is sales tax = 0.0825x. The coefficient, 0.0825, is the current tax rate of 8.25%. The variable, x, is the amount of your purchase.

## Math in the Real World

Required ResourcesRead/review the following resources for this activity:

• Textbooks: Review all chapters
• Minimum of 1 outside scholarly source (in addition to the textbook)

Instructions-It’s not hard to find interesting examples of math in the real world because math is everywhere, including advertising. Whether an airline is touting the amount you will save flying with them or a toothpaste company is informing you that 4 out of 5 dentists recommend their product, using math is one way advertisers try to get you to buy their product or service.

For this final discussion, find an online advertisement or news article that uses math. Include the following in your post:

3. Determine if this is an effective way to promote their product. Why or why not?

## Let’s Look at Ratios

Required ResourcesRead/review the following resources for this activity:

• Textbook -(Pre-Algebra): Chapter 5, 6
• Minimum of 1 outside scholarly source (in addition to the textbook)

Instructions-Did you drive to work today? If you did, you used a ratio. Driving 30 miles per hour involves a ratio of two numbers. It can be written as a fraction: (30 miles)/(1 hour), or the way we most commonly see it: 30 mph.

identifying other ratios we see in our everyday lives.

1. Think of an example of a ratio you use in your life or in the workplace.
2. List the ratio and explain its meaning in context of the application.
3. Create an equivalent fraction of the ratio that you presented and explain why equivalent fractions would be used in this application.
