Simplest Form- When you find the smallest number that goes into both the top and bottom,
Example: 6/9 divided by 3 is 2/3.
Adding Fractions- If both the bottom numbers are the same, you just add the top numbers.
Example: 2/3 + 1/3 = 3/3 = 1
If the bottom numbers are different, you need to find a number that both the numbers go into.
Example: 2/3 +1/4. 3 and 4 both go into 12. So you will have 8/12 + 3/12 = 11/12
Subtracting Fractions- Same method as adding fractions.
Example: 2/3 - 1/4. 3 and 4 both go into 12. so you will have 8/12 - 3/12 = 5/12
Multiplying Fractions- Times across. Top x Top. Bottom x Bottom.
Divide Fractions- Flip the Second Number Upsidedown and Times across.
2/3 divided by 1/4. 2/3 x 4/1. 2 x 4 = 8. 3 x1 =3. =8/3 = 2 and 2/3.
