Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Percent

A percent is a way of expressing a number as a fraction of 100. The term 'percent' comes from the Latin phrase 'per centum,' meaning 'by the hundred.' For example, 8% means 8 out of every 100, which can be represented as the fraction 8/100.

Simplifying Fractions

Simplifying a fraction involves reducing it to its lowest terms, where the numerator and denominator have no common factors other than 1. This is done by dividing both the numerator and denominator by their greatest common divisor (GCD). For instance, the fraction 8/100 can be simplified by dividing both by 4, resulting in 2/25.

Lowest Terms

A fraction is in lowest terms when the numerator and denominator are coprime, meaning they share no common factors other than 1. This ensures that the fraction is expressed in its simplest form, making it easier to understand and use in calculations. For example, 2/25 is in lowest terms, while 8/100 is not.
