Algebra 1 Lesson 6 1 Answer Key.In Module 4, students deepen their understanding of ratios and proportional relationships from Module 1 by solving a variety of percent problems. They convert between fractions, decimals, and percents to further develop a conceptual understanding of percent and use algebraic expressions and equations to solve multi-step percent problems. Students begin the module by solving problems without using a calculator to develop an understanding of the reasoning underlying the calculations. To develop a conceptual understanding, students use visual models and equations, building on their earlier work with these.

Example 2. Example 3. Example 4. Example 5. Example 6. The percentage problems include three numbers. One number is the base B. It represents the total amount of something or the measure of something. The second number is the rate R.

The third number is the part P. It is the amount or the measure of the part. Note that all examples considered above fall into one general formula. There are three major types of percentage problems. Solving Type 1 percentage problems : Finding the Part In Type 1 percentage problems you are given the base B and the percentage rate R. The part P is unknown you should find. The basic formula to solve Type 1 percentage problems is. The formula converts the percentage rate R to the decimal r and then calculates the part P multiplying the base by this decimal.

Solution Apply the basic formula 1. Represent the percentage rate as a decimal and then multiply the base by this decimal:. Example 8 Find The percentage rate R is unknown you should find. The basic formula to solve Type 2 percentage problems is. Example 9 What percent is 4 of 80? Solution Apply the basic formula 2. Calculate the decimal rate and then convert it to the percentage rate multiplying by. Example 10 What percent is Number Solving Type 3 percentage problems : Finding the Base In Type 3 percentage problems you are given the part P and the percentage rate R.

The base B is unknown you should find. Before applying this formula, you should convert the percentage rate to the decimal dividing by Problem 1 :. What is 30 percent of ? Problem 2 :. What percent of is 75? Problem 3 :. Problem 4 :. Problem 5 :. Problem 6 :. Solution :. The picture given below clearly illustrates the answer for the given question. So, 30 percent of is So, 15 percent of is So, Lani spent 72 minutes of her workday in meeting. Let x be the original price of the book. Then, we have.

Han is riding at a constant speed of 16 miles per hour. Priya started riding a half hour before Han.In this problem, the percent is the unknown quantity!

We need to figure out how to find this unknown quantity. Every statement of percent can be expressed verbally as: " One number is some percent of another number. For example:.

Looking at this problem, it is clear that 8 is the part and 20 is the whole. Similarly, in the statement, " One number is some percent of another number. Thus the statement, " One number is some percent of another number. From previous lessons we know that the word "is" means equals and the word "of" means multiply.

Thus, we can rewrite the statement above:. Let's look at an example of this. You are given two numbers from the proportion above and asked to find the third. The percent is the unknown quantity in this problem. We need to find this unknown quantity. Note that in Problem 1 we did not have to cross multiply to solve the proportion. We will look at these last two problems below. In Problems 1, 2 and 3 we are given two numbers and asked to find the third by using a proportion.

However, the unknown quantity was different for each problem. Let's compare these problems in the table below. Red is used for the unknown quantity in each problem. We did this by letting a variable represent the unknown quantity and then substituting the given values into a proportion to solve for the unknown quantity.

Note that in all three percent statements, the whole always follows the word "of" and the part always precedes the word "is". This is not surprising since our original statement is, " One number is some percent of another number. However, in the interest of consistency, we will use proportions to solve percent problems throughout this lesson.

Now that we have solved a number of percent problems using proportions, we can go back to the type of problem presented at the beginning of this lesson: In Problems 8 through 10 we will solve real world problems, using different variables to represent the unknown quantity in each problem.

How many games is that? What percent of her money is spent? Given two of these numbers, we can find the third by substituting into one of the proportions below.

Directions: Solve each percent problem below using a proportion.Looking for video lessons that will help you in your Common Core Grade 6 math classwork or homework?
