Step-by-Step Conversion of 7/20 to Percentage
The formula to convert a fraction to a percentage is:
[ \text{Percentage} = \left(\frac{\text{Numerator}}{\text{Denominator}}\right) \times 100 ]
For our case:
-
Identify the numerator and denominator:
- Numerator = 7
- Denominator = 20
-
Use the formula: [ \text{Percentage} = \left(\frac{7}{20}\right) \times 100 ]
-
Calculate the fraction:
