It will almost be impossible to find a solution otherwise! It ouwld be like adding apples and oranges. You would have a bowl of fruit, but that's not what you are to find!

we are able to purely upload and subtract issues that are the comparable eg 5 apples + 3 apples = 8 apples even with the shown fact that we can't upload 5 apples + 3 oranges subsequently a million/4 + 2/3 = 3/12 + 8/12 = 11/12__using common denominator of 12

Yes... a common denominator is essential to being able to add and subtract fractions. It is unnecessary when multiplying or dividing

Subtracting, example: 4/3-2/4 change the bottom to 12 and then whatever you had to times each bottom number by to get twelve times it at the top of each as well.
I think you have to do it for adding.

yes you do. you can not add the two figures if the bottom is not the same: for example 1/2 + 3/4.
1/2 is equal to 2/4; so 2/4 + 3/4 = 5/4 or 1 1/4

No. Make up your own denominator. The ones under the other numbers are merely suggestions, and they are unnecessary. Think of them as trick questions.

yes when "+" or "-" you will have to find the common denominator...when you multiply your fractions you multiply straight across & i can't remember how you divide fractions!
