1. Addition and Subtraction Equations with Fractions SWBAT apply the subtraction property of equality to solve addition equations with fractions; apply the addition property of equality to solve subtraction equations with fractions

2. Review  What are the 2 things you always need to do when solving equations? Keep it balanced!Keep it balanced! Isolate the variableIsolate the variable  When adding or subtracting fractions what is needed? A common denominatorA common denominator

3. Examples  X + ½ = ¾  Y + (-5/8) = ¼  ½ = m – 3/5  ¾ = x – 1/12  X – (-3/10) = 3/5  X + 7 ¼= 13 3/8

4. Try These  h + 2 1/6 = 5 5/9 - 2 1/6 -2 1/6 - 2 1/6 -2 1/6 h = 5 5/9 – 2 1/6 h = 5 5/9 – 2 1/6 h = 5 10/18 – 2 3/18 h = 5 10/18 – 2 3/18 h = 3 7/18 h = 3 7/18  c – 3 7/8 = 1 ¾ + 3 7/8 +3 7/8+ 3 7/8 +3 7/8 c = 1 ¾ + 3 7/8 c = 1 ¾ + 3 7/8 c = 1 6/8 + 3 7/8 c = 1 6/8 + 3 7/8 c = 4 13/8 c = 4 13/8 c = 5 5/8 c = 5 5/8
