## Step-by-Step Solution: 40 is What Percent of 25?

Now that we know we want to find **40 is what percent of 25? **, 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 “40 is what percent of 25?”.**

### Step1: Write the Ratio as a Fraction

First, we can express “40 is what percent of 25?” as the fraction 40/25.

40 of 25 can be written as: 40 25

### 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 25 into 100

To find this number, divide 100 by 25:

100 25 = 4

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

Multiply both the numerator and denominator by 4:

4025 x 44

= 40 x 425 x 4

= 160100

### Step 4: The Numerator is Now the Percentage

Since our new denominator is 100, the numerator **160** represents the percentage

This step-by-step method of converting the ratio 40 : 25 to a fraction and then a percentage with a denominator of 100 allows us to calculate that **40 is 160% of 25**.

## 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:

40 of 25 can be written as: 40 25

### Step 2: Divide the Numerator by the Denominator

Use long division to divide the numerator by the denominator:

40 25 = 1.6

### Step 3: Multiply the Decimal by 100

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

1.6 x 100 = 160%

Therefore, by dividing 40/25 to 1.6 and then multiplying by 100, **the result is 160%**

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 **40 is 160% of 25**.

## Comparing the Two Methods

Let’s summarize the two methods we used to find the percentage “40 is what percent of 25?”:

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 40 : 25 to an equivalent percentage fraction. The fraction to decimal method indirectly converts the fraction 40/25 to a decimal and then a percentage.**

p>Both methods follow a clear step-by-step procedure to arrive at the same result that 40 is 160% of 25. Understanding multiple approaches builds flexibility in thinking through percentage problems.

## Standard Percentage of 25 Calculation Examples

Now that we have calculated that **40 is 160% of 25**, let’s explore what 5%, 10%, up to 95% of 25 would be.

**1.25 is 5% of 25**

**2.5 is 10% of 25**

**3.75 is 15% of 25**

**5 is 20% of 25**

**6.25 is 25% of 25**

**7.5 is 30% of 25**

**8.75 is 35% of 25**

**10 is 40% of 25**

**11.25 is 45% of 25**

**12.5 is 50% of 25**

**13.75 is 55% of 25**

**15 is 60% of 25**

**16.25 is 65% of 25**

**17.5 is 70% of 25**

**18.75 is 75% of 25**

**20 is 80% of 25**

**21.25 is 85% of 25**

**22.5 is 90% of 25**

**23.75 is 95% of 25**

**25 is 100% of 25**

## Conclusion
