Operations with Fractions

Adding Fractions/ Subtracting Fractions

Step 1: Make sure the bottom numbers (denominators) are the same by finding the least common denominators

Step 2: Add the top numbers (numerators) put the answer over the denominator

Step 3: Simplify if needed

Subtracting Fractions

  1. Same step as adding fractions
  2. Subtract the top two numbers (numerators) put the answer over the same denominator
  3. Simplify if needed

Example: 4/8 + 7/8=?

We'll the denominators are the same so the denominator is 8. The numerator is 11 because 4+7= 11. So the answer is 11/8. But we can't forget to simplify! 8 goes in to 11 once. The simplified improper fraction is 1 & 3/11.

Multiplying Fractions

  1. Multiply the two numerators (top numbers)
  2. Multiply the two denominators (bottom numbers)
  3. Simplify if needed

Dividing Fractions

  1. Keep the first fraction the same
  2. Change the division sign to a multipulcation sign
  3. Flip the second fraction
