Find a common denominator between the two fractions then work from there like you would normally.1.To do so, You can multiply the denominators. Then multiply the numerator by the last denominator. Then ONLY add or subtract the numerators.simplifying. If the #'s are both even, they can be divided by two. If they aren't, List the factors of the numerator and the denominator. Find the least common factor.(LCM).Then divide the numerator and the denominator by that
#.Keep going to get a fraction simplified all the way. Hope this helped!=D

Why is it inaccurate to simplify add the numerators if two fractions with unlike denominator?
Because that is not how addition of fractions is defined.
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,
When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?
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.
How do you add fractions using the least common denomanator?
Ok. First you make sure the denominator (bottom number) is the same on all the fractions. The easiest way to do this is to multiply the denominators together, then multiply each numerator by the opposite fractions denominator. This is the easiest way to do this, you will simplify later. ONLY DO THIS IF THE DENOMINATORS ARE DIFFERENT. If they are the same just add the numerators together to get your fraction. Then simplify.
Do you need to simplify when adding fractions?
You can either simplify then add or add then simplify your answer

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 is adding like fractions and adding unlike fractions the same?
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.
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 denometiors?
You look for a common denominator; convert the fractions to equivalent fractions with the denominator you found; then you do the addition itself.
How do you add multiple mixed fractions?
Find a common denominator, add the numerators, simplify if possible.
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.
Why do you need to use common denominator?
To get the right answer when you add or subtract unlike fractions.
How do you add improper fractions?
If the denominators are different, find a common denominator, convert the fractions to equivalent fractions with the same denominator, proceed with adding the numerators, put that total over the denominator, simplify if possible. If the denominators are the same, skip the conversion, proceed with adding the numerators, put that total over the denominator, simplify if possible.
How do you add fractions in 6th grade math?
Find a common denominator between the two and then add the numerators. FInally simplify.
How can the greatest common factor and least common multiple help you work with fractions?
Finding the GCF of the numerator and the denominator of a fraction and dividing them both by it will give you the simplest form of that fraction. Finding the LCM of unlike denominators and converting them to it will make it possible to add and subtract unlike fractions.
