Understanding Percentages

A percentage is a fraction expressed as a number out of 100. The term "percent" literally means "per hundred". Therefore, 40 out of 50 means what portion of 100 does 40 represent when compared to 50.

Calculating 40 out of 50 as a Percentage

There are two primary methods to solve this:

Method 1: Using the Fraction Method

1. Express as a fraction: Write 40 out of 50 as a fraction: 40/50.
2. Simplify the fraction: Divide both the numerator (40) and the denominator (50) by their greatest common divisor (GCD), which is 10. This simplifies the fraction to 4/5.
3. Convert to a decimal: Divide the numerator (4) by the denominator (5): 4 ÷ 5 = 0.8
4. Convert to a percentage: Multiply the decimal by 100: 0.8 x 100 = 80%

Therefore, 40 out of 50 is 80%.

Method 2: Using the Percentage Formula

The general percentage formula is:

(Part / Whole) x 100% = Percentage

In this case:

• Part = 40
• Whole = 50

Substituting these values into the formula:

(40 / 50) x 100% = 80%

This again confirms that 40 out of 50 is 80%.
