Operations With Fractions

Adding Fractions
Here are a few easy steps to get you going on fraction adding.
The Problem
Say your adding 6/4+5/3 the denominator is different. This means we need to find the least common denominator or l.c.d.
Changing The denominator
4x3=12 So our new denominator will be 12
Change
What ever you do on the bottom you have to do to the top so 6 would be 18 and and 5 would be 20
Step 4
Now add the top #s and keep the denominator the same
The Problem
Now we are subtracting 1/3-2 4/6
L.c.d.
Now for the least common denominator. In this case 4/6 is = to 2/3. So 1/3-2/3= 1/3 + 2 = ....
2 1/3
Two and one third! Now you can try your self bye.
Multiplication & Division
Multiplication and division are a bit more tricky. They have more steps and require more knowledge.
The Problem
For this MULTIPLICATION problem start bye writing out 5/6x6/11=__
Multiplying
Multiply the numerators and the denominators. Put the denominator answer on the bottom and the numerator awswer on the top. Simplify your answer if possible.
Getting the Answer
This is what your final product should look like.
G.C.F
Greatest common factor is the strategy for dividing too, but I recommend Keep change flip.
