Any fraction that represents less than half of a whole is considered less than one-half. A fraction is not a whole number, but instead it is a representation of a whole. Students who are successful at this have already generalized the rule: fractions greater than 1 have numerators larger than their denominators; those that are less than 1 have numerators smaller than their denominators; the rest are equal to 1. The fraction with the largest numerator is the biggest.
The fractions have the same denominators, so you just need to compare their numerators. Answer: If two fractions have same numerator, the fraction having greater denominator is smaller. If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
The six kinds of fractions are, proper fractions, improper fractions, mixed fractions, like fractions, unlike fractions and equivalent fractions. Fractions are actually two stacked integers, with the one above the line called the numerator and the one beneath it the denominator.
Numbers are negative -- and signified with a minus sign, or "-" -- when they are less than zero. Negative numbers work in reverse because as numbers increase their values lessen.
You can compare the values of negative fractions with like and unlike denominators through the numbers appearing in the fractions. Find two negative fractions with like denominators for example purposes. Compare the numerators.
The numerator that is greater in value indicates the greater fraction. Find two negative fractions with different denominators for example purposes. Multiply each fractions' numerators by the others' denominators, assigning each fraction's negative sign to its numerator. In this example, multiplying 8 and -3 equals , and multiplying -7 and 4 equals Compare the two products from the previous step. If the product that includes the first fraction's numerator is greater than the other product, the first fraction is greater in value; if the product is less than the second one, the fraction is less in value; and if they are equal, the fractions are equivalent.
