Step-by-Step Solution: What is 8.7% of 841?

Now that we know we want to find 8.7% of 841, let’s look at two different step-by-step methods we can use to solve this percentage problem. Each approach arrives at the same solution, but understanding different ways to think through the math builds flexibility and deeper learning.

Method 1: Convert the Percent to a Decimal and Multiply

One approach to finding 8.7 percent of 841 is to convert the percent to a decimal and multiply. Here are the steps:

Step 1: Identify the part and whole

The part is the amount we want as a percentage. In this case, it is 8.7%.

The whole is the total amount. In this case, the whole is 841.

Step 2: Write the percentage as a decimal by dividing it by 100:

8.7% = 8.7/100 = 0.087

Step 3: Multiply the decimal form of percentage by the whole amount:

0.087 * 841 = 73.167

Therefore, 8.7% of 841 is 73.167.

Let’s look at this visually:

8.7% * 841 = 8.7/100 * 841 = 0.087 *841 = 73.167

This approach of converting the percentage to a decimal and multiplying is straightforward and can be applied to any “percent of number” problem. The key is properly converting the percent to a decimal by dividing by 100.

Method 2: Finding Percentages Using Algebraic Equations

Another way to find 8.7% of 841 is to set up an algebraic equation and solve it. Here are the steps:

A proportion is an equation that states two ratios are equivalent. Here is the proportion formula:

Part/Whole = Percentage/100

Step 1: Define the Unknown Variable

Let’s define an unknown variable x to represent 8.7% of 841. In algebraic equations, variables are used to represent unknown values.

Step 2: Set Up the Equation

Using the variable x, we can set up an equation with the information given:

• The unknown variable x (Part) is the amount we want to find, which is 8.7% of 841
• The Whole is 841
• The Percentage is 8.7

Substitute into the equation:

In this case, we can multiply both sides of the equation by 841

841 *x/841 = 8.7/100 * 841

x = 8.7 /100 * 841 = 7316.7/100 = 73.167

Therefore, 8.7% of 841 is 73.167.

Comparing the Methods

Both methods arrive at the same solution:

• Method 1 gets the solution by converting 8.7% to 0.087 and multiplying by 841.
• Method 2 sets up an equation, defines a variable, and solves algebraically.

The decimal conversion method is straightforward, avoiding any algebra. But the algebraic method is more flexible for complex problems where defining variables and setting up equations is helpful.

Common Percentage Scenarios

Here are some common percentage scenarios and how to solve them:

Finding the Percentage Given the Part and Whole

What Percent of 841 is 73.167?

Step 1: Define the Unknown Variable

Let unknown variable x = the unknown percent we want to find..

Step 2: Set Up the Equation

Using the variable x, we can set up an equation with the information given:.

• The unknown variable x (Percentage) is the number we want to find.
• The Part is 73.167
• The Whole is 841

Substitute into the equation:

73.167/841 = x/100

Step 3: Solve the Equation

To isolate x, we can cross multiply as follows:

• Take the numerator of one side of the equation, which is 73.167
• Multiply it by the denominator of the other side of the equation, which is 100
• Set that equal to the numerator of the second half (x) multiplied by the denominator of the first half (841)

When written out, the cross multiplication looks like:

73.167 * 100 = x * 841

x * 841 = 73.167 * 100

Then we can solve the resulting equation:

x * 841 = 7316.7

x = 8.7

Therefore, the answer is that 8.7% of 841 is 73.167.

Finding the Whole Given the Percentage and Part

Here is the proportion formula:

Part/Whole = Percentage/100

We will now demonstrate how to utilize proportion formula to calculate the whole given the percentage and part through an example determining 73.167 is 8.7 Percent of What Number.
