About Fraction

In short, a fraction is a part of a whole. If an object is divided into two equal parts, the value of each part is half, or one-half, of the total number of objects. A fraction is expressed in the form ab, where a is called the numerator and b is called the denominator. Learn more about fraction concept in this Interactive Pizza Fractions

How to add fractions?

In addition to the Least Common Multiple method, adding fractions can be done manually on paper using the cross-multiplication method, which involves finding a common denominator by multiplying the two denominators, then multiplying the numerators crosswise and adding the results. You can see the fraction addition formulas along with examples below.

How to subtract fractions?

Subtracting fractions is the same as adding them, except you replace the addition operator with the subtraction operator. For fractions with the same denominator, subtract the second numerator from the first numerator. Keep the denominator the same.

For subtraction with different denominators, find a common denominator, cross-multiply the numerators, and then subtract the second from the first. For more details, see the formula and examples below.
