Step-by-Step Solution: 72 is What Percent of 480?
Now that we know we want to find 72 is what percent of 480? , 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 Ratio to Percentage
Fractions consist of a numerator and denominator. Fractions consist of a numerator and denominator. The numerator represents the number of pieces being considered, while the denominator is the total number of pieces that make up the whole.
“Percent” means “per hundred”. So percent is another way to express a fraction where the denominator is always 100.
For example, the percentage 50% indicates we have 50 out of a total of 100 pieces. 50% can be rewritten as the fraction 50/100, since we have 50 parts out of 100 total parts.
In summary, to convert a fraction to a percentage, we multiply the numerator and denominator by the same value so that the denominator becomes 100. Once we have a fraction with a denominator of 100, the numerator gives us the percentage amount. This allows any fraction to be converted to an equivalent percentage based on the concept of “out of 100”.
Let’s apply this understanding to calculate “72 is what percent of 480?”.
Step1: Write the Ratio as a Fraction
First, we can express “72 is what percent of 480?” as the fraction 72/480.
72 of 480 can be written as: 72 480
Step 2: Find the Number to Multiply to Get a Denominator of 100
We want the denominator to be 100, so need to multiply by a number that makes 480 into 100
To find this number, divide 100 by 480:
100 480 = 0.208333333
Step 3: Multiply the Fraction by the Number from Step 2
Multiply both the numerator and denominator by 0.208333333:
72480 x 0.2083333330.208333333
= 72 x 0.208333333480 x 0.208333333
= 15100
Step 4: The Numerator is Now the Percentage
Since our new denominator is 100, the numerator 15 represents the percentage
This step-by-step method of converting the ratio 72 : 480 to a fraction and then a percentage with a denominator of 100 allows us to calculate that 72 is 15% of 480.
Method 2: Converting Fractions to Decimals and Percents
You can also use division to convert a fraction to a decimal and then to a percentage.
Step 1: Write the Fraction
Start with the original fraction:
72 of 480 can be written as: 72 480
Step 2: Divide the Numerator by the Denominator
Use long division to divide the numerator by the denominator:
72 480 = 0.15
Step 3: Multiply the Decimal by 100
To convert the decimal to a percentage, multiply it by 100:
0.15 x 100 = 15%
Therefore, by dividing 72/480 to 0.15 and then multiplying by 100, the result is 15%
Following this process carefully of dividing the fraction, multiplying the decimal by 100, and interpreting the result as a percentage provides us another method to find that 72 is 15% of 480.
Comparing the Two Methods
Let’s summarize the two methods we used to find the percentage “72 is what percent of 480?”:
Method | Description | Steps |
---|---|---|
Convert Ratio to Percentage | Converts the ratio to a fraction, then multiplies to make the denominator 100 | 1. Write ratio as fraction 2. Multiply to make denominator 100 3. Numerator is the percentage |
Convert Fraction to Decimal and Percentage | Divides the fraction to a decimal, then multiplies the decimal by 100 | 1. Write the fraction 2. Divide numerator by denominator 3. Multiply decimal by 100 4. Result is the percentage |
The ratio to percentage method directly converts the ratio 72 : 480 to an equivalent percentage fraction. The fraction to decimal method indirectly converts the fraction 72/480 to a decimal and then a percentage.
p>Both methods follow a clear step-by-step procedure to arrive at the same result that 72 is 15% of 480. Understanding multiple approaches builds flexibility in thinking through percentage problems.
