A percentage is a number representing a part of a whole, expressed as a fraction with a numerator and denominator. For example, 50% can be written as 1/2, indicating that 50 out of 100 parts of the whole are occupied by the given part.
Similarly, a fraction represents a portion of a whole, but it's broken down into equal parts with a specific unit. For instance, if we have 1/4 of a cake, it means that each part is equal to 1/4 of the entire cake.
When dealing with speed, both percentage and fraction representations are used to indicate relative distances or relative speeds. However, they represent the same information in different units.
Converting a percentage to a fraction is straightforward:
Divide the percentage by 100. This effectively converts it into a fraction with a numerator of 1 and a denominator of the given percentage.
Simplify the fraction by finding the greatest common factor of the numerator and denominator. This ensures the fraction is expressed in its simplest form.
Converting a fraction to a percentage is also simple:
Multiply the numerator by 100. This represents the percentage of the whole unit.
Divide the numerator by the denominator. This simplifies the fraction to its simplest form.
Examples:
50% as a fraction: 50/100 = 1/2
3/4 as a percentage: 3/4 x 100 = 75%
2/3 as a fraction: 2/3 = 4/6 (common factor is 2)
1/3 as a percentage: 1/3 x 100 = 33.33%
Tips:
Remember that fractions with the same denominator represent the same relative portion of the whole.
Pay attention to the context when interpreting the percentage; it might be expressed directly or indirectly.
