9. Adding Fractions 1. Make sure bottom numbers(denominators) are the same 2. Add the top numbers (numerators) E.g. 1

10. Adding Fractions E.g. 2 If the bottom numbers are different, find a COMMON DENOMINATOR (lowest common multiple) Common Denominator = 6

12. Subtracting Fractions Make sure bottom numbers (denominator) are the same 2. Subtract top numbers(numerator) * Remember keep BOTTOM NUMBER the same! E.g.1

13. Subtraction Fractions E.g. What if denominators are different? FIND COMMON DENOMINATOR (lowest common muiltple) Common Denominator=6
