Fun with Fractions!!

So am I the only one out there that has a hard time remembering how to add and subtract fractions? Oh, and don't forget about multiplying and dividing them too! Yikes! I just have such a difficult time remembering which need to have the same dividend and which don't, and which need to be switched around and which don't! Well, hopefully this blog will come in handy for any others that may have a hard time how to do each of them.

Let's start with adding fractions.........
There are three simple steps to add fractions:
  • Step 1: Make sure the bottom numbers (the denominators) are the same.
  • Step 2: Add the top numbers (the numerators), put the answer over the denominator.
  • Step 3: Simplify the fraction (if needed).



Now on to subtracting fractions, which is very similar to adding them......
There are also three simple steps to subtract fractions:
  • Step 1: Make sure the bottom numbers (the denominators) are the same.
  • Step 2: Subtract the top numbers (the numerators), put the answer over the denominator.
  • Step 3: Simplify the fraction (if needed).



On to multiplying fractions..................
There are three basic steps to this one:
  • Step 1: Multiply the top numbers (the numerators).
  • Step 2: Multiply the bottom numbers (the denominators).
  • Step 3: Simplify the fraction (if needed).


Now for the dividing of fractions......
Another three easy steps:
  • Step 1: Turn the second fraction (the one you want to divide) upside down. (This is now a reciprocal.)
  • Step 2: Multiply the first fraction by that reciprocal.
  • Step 3: Simplify the fraction (if needed).



I hope that this helps all of those out there that may have been a bit confused on fractions. I am also including a link that has some wonderful worksheets that may help in your classroom.
