When you're dividing fractions ... or multiplying thrm ... they don't need to have the same denominator.


How to change dissimilar fractions to similar fractions?

Note: numerator is the top part of the fraction, denominator is the bottom part. 1) Find a common denominator. It may be the least common denominator, but it need not be; just multiplying the denominators also gives you a common denominator, not necessarily the smallest one. 2) Convert each fraction so that it has this common denominator. This means multiplying numerator and denominator by the same number.


Do you need a common denominator for all fractions before doing the order of operations?

You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.


Do you need a common denominator for dividing fractions?

No only when adding or subtracting fractions a common denominator is needed


Does division need a common denominator?

No, You only need a common denominator when adding or subtracting fractions.


Why do you need a common denominator?

Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.


Do you need a common denominator to divide fractions?

No. Dividing fractions is achieved by inverting the divisor and multiplying the resulting fractions. To multiply fractions the numerators are multiplied together to form the new numerator and the denominators are multiplied together to form the new denominator.

How do you multiply fractions with whole numbers?

Fractions are multiplied by multiplying numerator by numerator and denominator by denominator. The fractions may be simplified before multiplying. Whole numbers have the understood denominator of 1. Read this lesson on multiplying fractions if you need help on how to multiply fractions.you multiply the denomanators and the top number then multiply the whole #s then reduce your answer if you can. an example would be 3 8/9X6 8/9= 18 64/81 get it now?


Adding and subtracting unlike denominators?

Fractions can only be added or subtracted if the denominators are the same. If the denominators are different, then the fractions need to be made into equivalent fractions with the same denominator. The new denominator can be found simply by multiplying the denominators together, but this can lead to some large fractions with which to work. A better new denominator is the lowest common multiple of (all the) denominators. (Once the new denominator is found, the fractions' new numerators are found by multiplying their current numerator by the new denominator divided by their current denominator to make their equivalent fractions with the new denominator.) Once all the fractions are converted into equivalent fractions with the new denominator then the fractions can be added or subtracted, with the result being simplified (if possible).


Do you need a common denominator when adding fractions?

yes


Do you need common denominator when adding fractions?

How do you subtract fractions in simplest form?

You first need to find a common denominator, not necessarily the least common denominator. Next, you rename the fractions according to the common denominator. Only then can you subtract the fractions. After subtraction you should simplify the answer.
