Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Percentages
A percentage represents a part per hundred and is denoted by the symbol '%'. To convert a percentage to a fraction, you place the percentage value over 100. For example, 35% means 35 out of 100, which can be expressed as the fraction 35/100.
Simplifying Fractions
Simplifying a fraction involves reducing it to its lowest terms by dividing both the numerator and the denominator by their greatest common divisor (GCD). For instance, the fraction 35/100 can be simplified by dividing both 35 and 100 by 5, resulting in 7/20.

Lowest Terms
A fraction is in lowest terms when the numerator and denominator have no common factors other than 1. This means that the fraction cannot be simplified any further. For example, 7/20 is in lowest terms because 7 and 20 share no common factors.
