Decompose fractions is part of 4th grade math course. Decomposing fractions means a fraction is written as sum (or difference) of two or more fractions. For example, 5/8 = 2/8 + 3/8 = 6/8 – 1/8. Fraction decomposition requires the numerator to be written as a sum (or difference) and then split the fraction as in the example given here. Learn more about how to decompose a fraction from the resources of this page.

A unit fraction is a rational number written as a fraction where the numerator is one and the denominator is a positive integer. A unit fraction is therefore the reciprocal of a positive integer, 1/n. Examples are 1/1, 1/2, 1/3, 1/4 ,1/5, etc.
Decompose is the process of separating numbers into their components (to divide a number into smaller parts).
The fractions above all have the same numerator. (Each of these fractions is called a unit fraction.) As the denominator gets larger, the fraction gets smaller. To compare fractions with like numerators, look at the denominators.
Equivalent fractions are fractions that look different but show exactly the same amount. You can make equivalent fractions by multiplying or dividing the numerator and denominator by the same number. You can simplify fractions by dividing the numerator and denominator by the same number.
