How fraction to decimal calculator works

This calculator converts a fraction (a numerator divided by a denominator) into its decimal equivalent. It divides the numerator by the denominator and rounds the result to 10 decimal places for display.

It also shows the simplified form of the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD). For example, the fraction 6/8 simplifies to 3/4 because the GCD of 6 and 8 is 2.

Fractions where the denominator is zero are rejected, as division by zero is undefined. The calculator handles both positive and negative fractions.

Frequently asked questions

How do I convert a fraction to a decimal?
Divide the numerator (top number) by the denominator (bottom number). For example, 3/4 becomes 3 divided by 4 = 0.75. The calculator does this automatically.
How do I simplify a fraction?
Find the greatest common divisor (GCD) of the numerator and denominator, then divide both by it. For example, 6/8 has GCD 2, so it simplifies to 3/4.
What happens with a zero denominator?
Division by zero is undefined, so the calculator shows an error. Any fraction with a zero denominator is mathematically invalid.
Does it handle negative fractions?
Yes. Enter a negative numerator or denominator and the calculator handles the sign correctly, producing the correct decimal and simplified fraction.
