What is a fraction visualizer?

A fraction visualizer is a tool that draws a fraction as a colored diagram — either a pie chart (circle split into parts) or a bar — so you can see what the fraction represents rather than just reading numbers.

How do I read the pie chart?

The circle is divided into sections equal to the denominator. The filled (colored) sections equal the numerator. For example, 3/4 shows three filled quarters out of four.

What are equivalent fractions?

Equivalent fractions are fractions that represent the same value but use different numbers. For example, 1/2 = 2/4 = 3/6. The tool shows several equivalents by multiplying the numerator and denominator by the same integer.

Can I enter improper fractions?

Yes. If the numerator is larger than the denominator (e.g. 5/3), the bar chart extends beyond full and the pie chart fills completely and shows the remainder. The decimal and percentage values update accordingly.

What does the simplified form show?

Simplification divides both the numerator and denominator by their greatest common divisor (GCD), producing the smallest whole-number fraction with the same value. For example, 6/9 simplifies to 2/3.
