When you add a fraction with different denominators, you must first have to find a common denominator. When you are done figuring out what the common denominator is, you can add both fractions. Finding common denominators are easy, but it takes a lot of courage. You have to remember to do the same thing for both numerators and denominators.(what you do to the bottom, you always do to the top) After you do these steps, adding fractions would be easier for you.
Subtracting fractions is like doing adding fractions. The only different thing you have to do is to subtract. You use the same steps but instead of adding, you will do subtracting. As I said before, it will become easier when you practice and practice and it really takes a lot of courage to do this.
After you figure out the answer to the fractions your adding or subtracting, before handing your work in, you will have to find it's lowest term. Lowest term means when you get a huge fraction and you find it's lowest term. You will then have to find what number your going to use to divide in order to get it's lowest term. I will show you an example below.
