Any fraction with a one as the numerator and a number equal to or greater than three as the denominator will be less than 1/2. As a general rule, if the denominator is more than twice as large as the numerator, the fraction will be smaller than 1/2. For example, 2/9 is less than 1/2.
Know MoreIn order to compare the size of fractions, they must have a common denominator. With a common denominator, the fraction with a smaller numerator is smaller. As an example, 1/2 and 2/9 could be re-written as 9/18 and 4/18 respectively. It is clear that 4/18, or 2/9 is the smaller of the pair.

Egyptians created a number system on a base 10 concept, which is similar to the numerical systems used in the United States and around the world for creating fractions. Originally, Egyptians used pictures as well as numerals to display and differentiate numbers.
Full Answer >To subtract fractions, make sure the bottom numbers (denominators) are the same, then subtract the top numbers (numerators) from one another, retaining the denominator and simplifying if required. This process can be done by hand or by using a calculator.
Full Answer >Equivalent fractions are fractions that have the same numerical value. For example, 1/2 and 2/4 are equivalent fractions, as they are both equal to 0.5.
Full Answer >Add and subtract fractions by finding like denominators and then adding or subtracting the numerators. To multiply fractions, simply multiply the numerators and denominators together. To divide fractions, multiply the first fraction by the inverse of the second fraction. Finish by simplifying your answer.
