Fraction to Decimal
Divide the top number by the bottom number.
📐 The Formula
A fraction is essentially a division problem. To convert it to a decimal, you simply divide the numerator (top number) by the denominator (bottom number).
Formula:
Numerator ÷ Denominator = Decimal
Example: To convert 3/4:
3 ÷ 4 = 0.75

❓ Frequently Asked Questions
1. How do I turn a fraction into a percentage?
First, convert the fraction to a decimal by dividing the top by the bottom. Then, multiply the result by 100. Example: 1/2 = 0.5 → 0.5 * 100 = 50%.
2. What is a repeating decimal?
Some fractions, like 1/3, result in a decimal that never ends (0.3333...). This is called a repeating decimal.
3. Can the denominator be zero?
No. In mathematics, you cannot divide by zero. If you enter 0 as the denominator, the result is "undefined."
4. How do I convert mixed numbers?
If you have a mixed number like 2 1/2, keep the whole number (2) and convert the fraction (1/2 = 0.5). Combine them to get 2.5.
5. Why are decimals useful?
Decimals are often easier to compare, order, and add up, especially when dealing with money or scientific measurements.
