Percentage Practice Problems & Word Problems with Solutions

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%.

To solve this problem, we'll proceed with the following steps:

• Step 1: Identify the given information
  We are given a percentage of 3% and a whole number of 100.
• Step 2: Use the percentage formula
  The formula to calculate the percentage of a whole number is given by:
  $\text{Percentage value} = \frac{\text{percentage}}{100} \times \text{whole number}$
• Step 3: Substitute the values and calculate
  Substituting the given values into the formula, we have:
  $\frac{3}{100} \times 100 = 3$

Therefore, the 3% of 100 is $3$.

To solve this problem, we'll follow these steps:

• Step 1: Identify the given fraction $\frac{32}{100}$.
• Step 2: Recognize that the denominator of 100 aligns directly with the meaning of percentage.
• Step 3: Conclude that when the fraction is $\frac{\text{Part}}{100}$, it equals $\text{Part}\%$.

Now, let's work through each step:

Step 1: The problem gives us the fraction $\frac{32}{100}$.
Step 2: Since the denominator is 100, the fraction directly represents a percentage.
Step 3: This means that $\frac{32}{100}$ is simply $32\%$.

Therefore, the solution to the problem is $32\%$.

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 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%.
