Step-by-Step Solution: What is 20% of 15000?

Now that we know we want to find 20% of 15000, 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 20 percent of 15000 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 20%.

The whole is the total amount. In this case, the whole is 15000.

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

20% = 20/100 = 0.2

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

0.2 * 15000 = 3000

Therefore, 20% of 15000 is 3000.

Let’s look at this visually:

20% * 15000 = 20/100 * 15000 = 0.2 *15000 = 3000

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 20% of 15000 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 20% of 15000. 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 20% of 15000
• The Whole is 15000
• The Percentage is 20

Substitute into the equation:

In this case, we can multiply both sides of the equation by 15000

15000 *x/15000 = 20/100 * 15000

x = 20 /100 * 15000 = 300000/100 = 3000

Therefore, 20% of 15000 is 3000.

Comparing the Methods

Both methods arrive at the same solution:

• Method 1 gets the solution by converting 20% to 0.2 and multiplying by 15000.
• 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.

We will now demonstrate how to utilize proportion formula to calculate the percentage given a part and whole amount through an example determining what percent of 15000 is 3000.

What Percent of 15000 is 3000?

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 3000
• The Whole is 15000

Substitute into the equation:

3000/15000 = 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 3000
• 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 (15000)

When written out, the cross multiplication looks like:

3000 * 100 = x * 15000

x * 15000 = 3000 * 100
