Step-by-Step Solution: What is 20% of 300000?
Now that we know we want to find 20% of 300000, 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 300000 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 300000.
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 * 300000 = 60000
Therefore, 20% of 300000 is 60000.
Let’s look at this visually:
20% * 300000 = 20/100 * 300000 = 0.2 *300000 = 60000
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 300000 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 300000. 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 300000
- The Whole is 300000
- The Percentage is 20
Substitute into the equation:
In this case, we can multiply both sides of the equation by 300000
300000 *x/300000 = 20/100 * 300000
x = 20 /100 * 300000 = 6000000/100 = 60000
Therefore, 20% of 300000 is 60000.
Comparing the Methods
Both methods arrive at the same solution:
- Method 1 gets the solution by converting 20% to 0.2 and multiplying by 300000.
- 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.
