# Operations with Fractions

### By: Tyler

## 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

- Same step as adding fractions
- Subtract the top two numbers (numerators) put the answer over the same denominator
- 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

- Multiply the two numerators (top numbers)
- Multiply the two denominators (bottom numbers)
- Simplify if needed

## Dividing Fractions

- Keep the first fraction the same
- Change the division sign to a multipulcation sign
- Flip the second fraction
