Step-by-Step Solution: 378 is What Percent of 450?

Now that we know we want to find 378 is what percent of 450? , 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 “378 is what percent of 450?”.

Step1: Write the Ratio as a Fraction

First, we can express “378 is what percent of 450?” as the fraction 378/450.

378 of 450 can be written as: 378 / 450

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 450 into 100

To find this number, divide 100 by 450:

100 /450 = 0.222222222

Step 3: Multiply the Fraction by the Number from Step 2

Multiply both the numerator and denominator by 0.222222222:

378/450 x 0.222222222/0.222222222
= 378 x 0.222222222/450 x 0.222222222
= 84/100

Step 4: The Numerator is Now the Percentage

Since our new denominator is 100, the numerator 84 represents the percentage

This step-by-step method of converting the ratio 378 : 450 to a fraction and then a percentage with a denominator of 100 allows us to calculate that 378 is 84% of 450.

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:

378 of 450 can be written as: 378 / 450

Step 2: Divide the Numerator by the Denominator

Use long division to divide the numerator by the denominator:

378 / 450 = 0.84

Step 3: Multiply the Decimal by 100

To convert the decimal to a percentage, multiply it by 100:

0.84 x 100 = 84%

Therefore, by dividing 378/450 to 0.84 and then multiplying by 100, the result is 84%

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 378 is 84% of 450.

Comparing the Two Methods

Let’s summarize the two methods we used to find the percentage “378 is what percent of 450?”:

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 378 : 450 to an equivalent percentage fraction. The fraction to decimal method indirectly converts the fraction 378/450 to a decimal and then a percentage.

p>Both methods follow a clear step-by-step procedure to arrive at the same result that 378 is 84% of 450. Understanding multiple approaches builds flexibility in thinking through percentage problems.
