Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Percentages
A percentage represents a fraction out of 100. It is a way to express a number as a part of a whole, making it easier to compare different quantities. For example, 15% means 15 out of every 100, which can be useful in various applications such as finance, statistics, and everyday calculations.
Fractions
A fraction consists of a numerator and a denominator, representing a part of a whole. To convert a percentage to a fraction, you place the percentage value over 100. For instance, 15% can be expressed as 15/100, which can then be simplified to its lowest terms by dividing both the numerator and denominator by their greatest common divisor.
A fraction is in lowest terms when the numerator and denominator have no common factors other than 1. To simplify a fraction, you divide both the numerator and denominator by their greatest common factor. For example, the fraction 15/100 can be simplified to 3/20, as both 15 and 100 can be divided by 5.
