Percents: Your Assignments for January 8th - 17th, 2014
Welcome to a new cycle of learning in Professor Baker's Math Class! This page details all the assignments you'll be working on from January 8th to January 17th, 2014. We'll be focusing on percents, a fundamental concept with applications in many real-world scenarios, from calculating discounts to understanding financial data.
Homework Packet
Your primary resource for this cycle is the attached packet. Make sure you have a copy and are ready to tackle the problems. Here's the breakdown of the assigned pages and problems:
- 01-08: Pg. 427-428 #1-34
- 01-09: Pg. 428 #35-40
- 01-10: Pg. 428 #41-46
- 01-13: Pg. 428-429 #47-52
- 01-14: Pg. 429 #53, 54, 61-63
Percent Project
On January 15th and 16th, you'll be working on a Percent Project. The rubric for this project is attached, outlining the expectations and grading criteria. This project is designed to help you apply your knowledge of percents in a practical way, such as finding six uses of percent on the internet, four used correctly and two used incorrectly.
Key Concepts: Understanding Percents
Percents are all about expressing numbers as a part of 100. The term "percent" literally means "per hundred." For example, if we say 57% of houses have three bedrooms, it means 57 out of every 100 houses have three bedrooms. Mathematically, we represent this as:
$$ \frac{57}{100} = 57\% $$Here's how to convert between fractions, decimals, and percents:
- Fraction to Percent: Divide the numerator by the denominator, multiply by 100, and add a percent sign. For example, to express $\frac{5}{8}$ as a percent:
- $\frac{5}{8} = 0.625$
- $0.625 \times 100 = 62.5$
- $\frac{5}{8} = 62.5\%$
- Decimal to Percent: Move the decimal point two places to the right and add a percent sign. For example, $0.47 = 47\%$.
- Percent to Decimal: Move the decimal point two places to the left and remove the percent sign. For example, $19\% = 0.19$.
Real-World Applications
Percents are used everywhere! From calculating sales tax to understanding statistics, they are an essential tool. For example, if a charity has raised $16,400 out of an $80,000 goal, the percentage of the goal raised can be calculated as follows:
$$ \frac{\text{Amount Raised}}{\text{Total Goal}} = \frac{16400}{80000} = 0.205 = 20.5\% $$This means the charity has raised 20.5% of its goal.
Percent Test
On January 17th, you will have a test on percents. Make sure you understand the concepts covered in the homework and project to prepare effectively.
Occupational Interview
Don't forget the Occupational Interview! This assignment is due on February 4th, 2014. Use the interview sheet that was passed out to guide your conversation and document your findings.
Remember to stay focused, ask questions, and utilize all the resources available to you. Good luck with your work on percents!
