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
Because that is not how addition of fractions is defined.
no, to add and subtract like and unlike fractions the denominator has to be 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.
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.
No.

You look for a common denominator; convert the fractions to equivalent fractions with the denominator you found; then you do the addition itself.
You first convert them to equivalent fractions with a common denominator. Or you convert them to decimal fractions.
To get the right answer when you add or subtract unlike 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.
Find a common denominator between the two and then add the numerators. FInally simplify.
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.
The question is based on a complete misunderstanding of what is required. Unlike denominators are NOT required!
