1. How do you add a fraction?
Step 1 Make sure your denominators are the same

Step 3 Reduce (Simplify your fraction if possible
2. How do you subtract a Fraction?
Step 1 Make sure your denominators are the same, If not find a common denominator

Step 2 Subtract your top numbers and put them over denominator

Step 3 Reduce if possible
3. How to Multiply a Fraction
• When multiplying fractions just simply multiply straight across and reduce if possible
• Example: 2/3 x 2/5= 4/15
4. How to Divide a Fraction
Step 1 Flip the second fraction for example 1/2 will become 2/1

Step 2 Multiply the fraction by the reciprocal (fraction you just flipped)

Step 3 Reduce if possible
5. Is this an example of adding a fraction the correct way? 1/2+3/4= 4/6
NO. We need to find a common denominator which would be 4! So we would find out how many times two goes into 4 and what you do to the bottom you must do to the top.
6. Is this how you multiply a fraction? 3/4 x 4/4= 12/16
YES, When multiplying we multiply STRAIGHT ACROSS and leave it as is!
7. Is this how I divide a fraction? 2/3 / 1/4=
2/3 * 4/1= 8/3
YES, We have flipped our reciprocal and multiplied straight across and out fraction is reduced to it's lowest terms
8. When subtracting fractions can I do this.. 2/6-1/6= 1/6?
YES, Because I already have two common denominators there for I do not have to find one. Now if I have 1/2-1/6 then I would have to find a common denominator and then subtract and reduce if needed.
