## Calculating What Percent X is of Y

The calculation to determine what percentage one number (X) is of another number (Y) is commonly used in various fields, such as finance, statistics, and general mathematics. This calculation helps in understanding the proportion of one value relative to another.

The formula to calculate what percent X is of Y is expressed as:

\( \text{Percentage} = \frac{X \times 100}{Y} \)

where:

**X**represents the first value.**Y**represents the second value.

By multiplying X by 100 and then dividing by Y, you obtain the percentage that X is of Y.

## Examples

The following examples demonstrate how to calculate what percent X is of Y using the given formula.

### 1. Sarah scored 18 marks out of 20 in her math test. What percentage of the total marks did she achieve?

#### Answer

Given:

**X**= 18 (Marks scored)**Y**= 20 (Total marks)

The formula to calculate the percentage is:

\( \text{Percentage} = \frac{X \times 100}{Y} \)

Substituting the given values:

\( \text{Percentage} = \frac{18 \times 100}{20} \)

Calculating the result:

\( \text{Percentage} = \frac{1800}{20} = 90\% \)

Therefore, Sarah scored 90% of the total marks.

### 2. A store sold 150 of its 600 inventory items during a sale. What percentage of the inventory was sold?

#### Answer

Given:

**X**= 150 (Items sold)**Y**= 600 (Total inventory)

The formula to calculate the percentage is:

\( \text{Percentage} = \frac{X \times 100}{Y} \)

Substituting the given values:

\( \text{Percentage} = \frac{150 \times 100}{600} \)

Calculating the result:

\( \text{Percentage} = \frac{15000}{600} = 25\% \)

Therefore, 25% of the inventory was sold during the sale.

### 3. Out of 80 employees in a company, 64 have completed the mandatory training. What percentage of employees have completed the training?

#### Answer

Given:

**X**= 64 (Employees completed training)**Y**= 80 (Total employees)

The formula to calculate the percentage is:

\( \text{Percentage} = \frac{X \times 100}{Y} \)

Substituting the given values:

\( \text{Percentage} = \frac{64 \times 100}{80} \)

Calculating the result:

\( \text{Percentage} = \frac{6400}{80} = 80\% \)

Therefore, 80% of the employees have completed the training.

### 4. A car's fuel tank holds 50 liters of fuel. If the car has 10 liters of fuel left, what percentage of the tank is still full?

#### Answer

Given:

**X**= 10 (Fuel left)**Y**= 50 (Total fuel capacity)

The formula to calculate the percentage is:

\( \text{Percentage} = \frac{X \times 100}{Y} \)

Substituting the given values:

\( \text{Percentage} = \frac{10 \times 100}{50} \)

Calculating the result:

\( \text{Percentage} = \frac{1000}{50} = 20\% \)

Therefore, 20% of the fuel tank is still full.
