Understanding Fractions and Percentages
Fractions and percentages are two different ways of representing parts of a whole.

Therefore, to convert a fraction into a percentage, we need to find out how much the fraction is equivalent to out of 100.
Key Terms
- Numerator: The top number of a fraction.
- Denominator: The bottom number of a fraction.
- Percentage: A fraction expressed as a part of 100.
The Formula to Convert Fraction to Percentage
To convert a fraction to a percentage, you can use the following formula:
[ \text{Percentage} = \left( \frac{\text{Numerator}}{\text{Denominator}} \right) \times 100 ]
For 13/19, we will use this formula for our calculations.
Step-by-Step Calculation of 13/19 as a Percentage
Step 1: Identify the Numerator and Denominator
For the fraction 13/19:
- Numerator = 13
