What is a Percentage?

Before diving into the conversion, let's briefly revisit the concept of percentages. A percentage is a way of expressing a number as a fraction of 100. The symbol "%" represents "per hundred". For instance, 50% means 50 out of 100, or 50/100.

Converting 40/50 to a Percentage: A Step-by-Step Guide

Converting a fraction like 40/50 to a percentage involves a straightforward two-step process:

Step 1: Divide the Numerator by the Denominator

The first step is to divide the numerator (the top number) by the denominator (the bottom number):

40 ÷ 50 = 0.8

Step 2: Multiply the Result by 100

To express this decimal as a percentage, multiply the result by 100:

0.8 x 100 = 80

Therefore, 40/50 is equal to 80%.

Simplifying the Fraction (Optional)

Before performing the division, you can simplify the fraction 40/50. Both the numerator and denominator are divisible by 10:

40/50 = 4/5

Now, divide 4 by 5:

4 ÷ 5 = 0.8

Multiply by 100:

0.8 x 100 = 80%

Simplifying the fraction first can make the calculation easier, especially with larger numbers.
