Quantity, percentage, percentage value: Express one number as a percentage of another

In order to determine what percentage 25 is out of 100, we use the following formula:

$\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100\%$

.

We begin by substituting in the known values:

$\text{Percentage} = \frac{25}{100} \times 100\% = 25\%$

.

Thus, 25 out of 100 is $25\%$.

In order to determine what percentage 75 is out of 100, we use the following formula:

$\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100\%$

.

We begin by substituting in the known values:

$\text{Percentage} = \frac{75}{100} \times 100\% = 75\%$

.

Thus, 75 out of 100 is $75\%$.

In order to determine what percentage 10 is out of 100, we use the following formula:

$\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100\%$

.

We substitute in the known values:

$\text{Percentage} = \frac{10}{100} \times 100\% = 10\%$

.

Thus, 10 out of 100 is $10\%$.

In order to determine what percentage 40 is out of 100, we use the following formula:

$\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100$

We begin by substituting in the known values:

$\text{Percentage} = \left( \frac{40}{100} \right) \times 100$

We then proceed to solve the expression:

$\text{Percentage} = 0.4 \times 100$

$\text{Percentage} = 40$

Thus, 40 out of 100 is 40%.

To find what percentage 65 is out of 100, use the formula:

$\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100$

Substitute the given values:

$\text{Percentage}=\left(\frac{65}{100}\right)\times100$

Solve the expression:

$\text{Percentage}=0.65\times100$

$\text{Percentage}=65$

So, 65 out of 100 is 65%.

In order to determine what percentage 30 is out of 100, you can use the following formula:

$\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100$

We begin by substituting the given values into the formula:

$\text{Percentage} = \frac{30}{100} \times 100$

We then proceed to simplify the expression:

$\text{Percentage} = 30\%$

Therefore, 30 out of 100 is 30%.

In order to determine what percentage 50 is out of 100, we use the following formula:

$\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100$

Input the known values into the formula:

$\text{Percentage} = \frac{50}{100} \times 100$

This simplifies to:

$\text{Percentage} = 50\%$

Hence, 50 out of 100 corresponds to 50%.

In order to determine the percentage of 75 out of 100, apply the percentage formula:

$\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100$

Substitute the specific values:

$\text{Percentage} = \frac{75}{100} \times 100$

The equation simplifies to:

$\text{Percentage} = 75\%$

Therefore, 75 out of 100 is equivalent to 75%.

In order to determine what percentage 25 is out of 125, we use the formula:

$\frac{\text{Part}}{\text{Whole}} \times 100$

We begin by substituting the given values into the formula:

$\frac{25}{125} \times 100$

We then divide 25 by 125:

$0.2$

Finally we multiply the result by 100 to convert it into a percentage:

$0.2 \times 100 = 20\%$

Thus, 25 is 20% of 125.

When calculating percentages, we need to know the following simple equation:

Using the two pieces of known data, we are able to calculate the percentage:

In this case, we know the percentage value - 45

And the initial quantity - 180

Therefore, we can insert this information into the formula:

X/100 = 45/180

We'll multiply by cross multiplication:

180X=45*100

180X=4500

Let's reduce:

18X=450

Divide by 18:

X=25

Hence the answer is 25%
