This is one of the assignments we have done for Adding and Subtracting Fractions:
1.) 1/12 + 3/4 =
2.) 1/4 + 1/2=
3.)1/8 - 3/8=
4.) 5/6 - 3/4=
5.)1/3 - 2/5=
2.) 1/4 + 1/2=
3.)1/8 - 3/8=
4.) 5/6 - 3/4=
5.)1/3 - 2/5=
What you need to do here is solve these problems by finding the LCD for each problems and the way you are going to do that is to take both denominators and try to find a common number that will times top and bottom of each fraction.
