Rational Numbers Any number that can be written as a fraction or Repeating Decimal Why? Because all repeating decimals can be written as fractions
![Rational Numbers We just said all repeating decimals must be able to be written Rational Numbers We just said all repeating decimals must be able to be written](http://slidetodoc.com/presentation_image_h/20b98cf3fbf19d9d44ff1f4ed7030adf/image-7.jpg)

Rational Numbers Lets say L = 0. 55555…. . Since only “one” number repeats…. The 5, we will multiply by 10 on both sides
![Rational Numbers L = 0. 55555…. . 10 L = 5. 55555…… Multiplying by Rational Numbers L = 0. 55555…. . 10 L = 5. 55555…… Multiplying by](http://slidetodoc.com/presentation_image_h/20b98cf3fbf19d9d44ff1f4ed7030adf/image-9.jpg)
Rational Numbers L = 0. 55555…. . 10 L = 5. 55555…… Multiplying by 10 moves a decimal over one time
![Rational Numbers L = 0. 55555…. . 10 L = 5. 55555…… - L Rational Numbers L = 0. 55555…. . 10 L = 5. 55555…… - L](http://slidetodoc.com/presentation_image_h/20b98cf3fbf19d9d44ff1f4ed7030adf/image-10.jpg)
Rational Numbers L = 0. 55555…. . 10 L = 5. 55555…… - L = 0. 55555…. . 9 L = 5 Subtract “L” from both sides now…. remember L = 0. 555…

Rational Numbers 10 L = 5. 55555…… - L = 0. 55555…. . 9 L = 5 ÷ 9 L = Solve for “L” by dividing by 9 on both sides
