# Fraction Calculator

Fractions are made up of a numerator and a denominator. The top number is the numerator and tells how many equal parts; the denominator is the lower number and represents how many parts make up a whole or one. Fractions are often used in mathematics because they are more accurate than the decimal equivalent. For instance, using 1/3 for multiplication is much more accurate than using the decimal equivalent.

Fractions can be represented by a decimal or percentage. A decimal fraction would be divided by 10, 100, 1000, etc depending on how far the decimal was carried. The decimal 0.3 could be represented as a fraction as 3/10. A percentage will always have 100 as the denominator.
