## Frequently Asked Questions

**Formula:**

Part Value = (Percentage / 100) * Total Value

**Explanation:**

To find a specific part value that represents a given percentage of the total value, multiply the percentage (as a decimal) by the total value.

**Example:**

If you want to find 25% of 200:

Part Value = (25 / 100) * 200 = 50

**Formula:**

Percentage = (Part Value / Total Value) * 100

**Explanation:**

To determine what percentage a part value is of the total value, divide the part value by the total value and multiply by 100.

**Example:**

If you have 50 and want to know what percentage it is of 200:

Percentage = (50 / 200) * 100 = 25%

**Formula:**

Total Value = (Part Value / Percentage) * 100

**Explanation:**

To find the total value when you know a part value and its corresponding percentage, divide the part value by the percentage (as a decimal) and multiply by 100.

**Example:**

If 50 is 25% of the total value:

Total Value = (50 / 25) * 100 = 200

**Formula:**

Increase Percentage = ((New Value – Old Value) / Old Value) * 100

**Explanation:**

To find the percentage increase from an old value to a new value, subtract the old value from the new value, divide by the old value, and multiply by 100.

**Example:**

If a value increased from 100 to 150:

Increase Percentage = ((150 – 100) / 100) * 100 = 50%

**Formula:**

Decrease Percentage = ((Old Value – New Value) / Old Value) * 100

**Explanation:**

To find the percentage decrease from an old value to a new value, subtract the new value from the old value, divide by the old value, and multiply by 100.

**Example:**

If a value decreased from 100 to 75:

Decrease Percentage = ((100 – 75) / 100) * 100 = 25%

**Formula:**

Percentage = (Part Value / Total Value) * 100

**Explanation:**

To find out what percentage one number is of another, divide the part value by the total value and multiply by 100.

**Example:**

If you want to know what percentage 50 is of 200:

Percentage = (50 / 200) * 100 = 25%
