To put fractions in order, first make sure that the denominators, or bottom numbers, are the same. Use the rule of least common denominator (LCD) as necessary. When the denominators are the same, put the fractions in order according to the numerators, or top numbers.
Know MoreBegin putting fractions in order by looking at the denominators. If all of the fractions have the same denominator, you do not perform any conversions and can move on to the next step.
If all of the denominators are the same, put the fractions in order by the numerators. For example: one-eighth, two-eighths, three-eighths, four-eighths and so on.
If the denominators are different from one another, find the least common denominator, and convert the fractions so all have the same denominator. For example, the least common denominator of one-half and two-sixths is six. The equivalent fractions are three-sixths and two-sixths.
Order the fractions by numerator once you have created fractions with the same denominator. Using the example in the previous step, the correct order would be two-sixths and three-sixths. Use the original fractions, and the correct order is two-sixths and one-half.
Multiply fractions by multiplying the numerators and then the denominators. The products provide the numerator and denominator of the result, which should then be simplified to the lowest terms.
Full Answer >To multiply improper fractions, multiply the fractions' numerators by each other for the product numerator, and multiply the denominators by each other for the product denominator. Then you have the option to simplify the improper fraction to a mixed fraction.
Full Answer >To add fractions, you must first make the denominators the same. The denominators are the bottom numbers of the fractions. When you add a negative fraction and a positive fraction, you are essentially subtracting one fraction from the other.
Full Answer >Fractions cannot be added unless they have like denominators. Therefore, to add fractions with unlike denominators, you have to convert one of the fractions so that it's expressed in terms of the other fraction. This is easiest to do by rewriting lower fractions to match higher ones.
