No but the denominators must be the same and you just add the numerators. If the denominators are different and you have to find which is greater you have to find a denominator that both numbers can multiply into. For example, 5/6 and 3/12 will be our fractions. 6 times to equals 12. Since 12 is the other denominator 3/12 stays the same. Thats the only time you can change the denominator.

When you add fractions do you add the denominator to?

No.


When you add fractions do they have to have the same denominator?

Yes you have to add with the same denominator. when ever you do fractions they have to have the same denominator no matter what. So thats a yes


How do you add fractions with unlike denometiors?

You look for a common denominator; convert the fractions to equivalent fractions with the denominator you found; then you do the addition itself.


Why do you need a common denominator with fractions?

You can add or subtract fractions only if they are "like" fractions, that is, only if they have the same denominator - unless you know your fractions really well.


What you need to add or subtract fractions?

You need a common denominator in order to add or subtract fractions.


How do I add improper fractions?

Change them into mixed numbers and add the integers and fractions together ensuring that the fractions have a common denominator.


When you add fractions do you have to have the same denominator?

Yes.

if it has a denominator


How do you add or subtract dissimilar fractions?

You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.


How do you add similar fractions?

Just add the numerators and copy the denominator.


Why do you need a common denominator when you add fractions?

Unless you are using a calculator that adds them for you, it is much harder to add fractions with uncommon denominators. Having the same denominator allows you to only have to add the numerators for your answer.


How do you add and subtract fractions with the same denominator?

it stay the same when you subtract fractions and when you add fractions.


How do you add fractions step by step?

you make fractions equivalent denominators, you add the numerators and put it over the denominator


How do you add fractions with the same denominator with whole numbers?

First you add the fractions then add the whole numbers I'd you can you can reduce the fractions bye multiplying Hope you have fun!😺🐆💙💎💖🐾


How do you add and subtract by fractions?

If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.


When do you add fractions when baking?

In order to add fractions, they must have the same denominators. If the fractions you wish to add do not already have the same denominators, they can be made to do so by finding the right number by which to multiply both the numerator and the denominator of each fraction. To find this number, multiply all the distinct denominators together, then multiply both the numerator and denominator of each fraction by a number found by the dividing the product of the distinct denominators by the denominator of the particular fraction concerned. All the fractions will then have the same denominator. Add the numerators of such fractions together to find the numerator of the sum; its denominator will be the one common to all the fractions.


When you add fractions do you find the common denominator?

Yes you do.


When you add fractions are you supposed to have the same denominator?

Yes, you are.


How do you add two fractions with a different denominator?

You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.


Adding unlike fractions?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.


How are fractions under addition?

In order to add or subtract fractions, they must have the same denominator.


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 add and subtract like and unlike fractions in the same way?

no, to add and subtract like and unlike fractions the denominator has to be the same,


How do you add fractions with unlike denomanators?

You first convert them to equivalent fractions with a common denominator. Or you convert them to decimal fractions.


How to add fractions having similar numerators but different denominators?

The first step, to add, subtract, or compare fractions, is always to convert the fractions to equivalent fractions, that all have the same denominator. You can use one of several techniques to get the LEAST common denominator, or simply multiply the two denominators to get a common denominator (which in this case may, or may not, be the smallest common denominator).
