  1. Converting Decimals/Fractions

  2. Essential Question (EQ): Explain the two steps needed to convert from a decimal number to a fraction. Explain the process of converting a fraction to a decimal. Reducing to Lowest Terms There are two different ways to reduce a fraction to lowest terms. 1. Keep _______ the __________ (top) & ___________ (bottom) by the common _________ until they don’t have anything else in common. 84/100 example on board denominator dividing numerator factors

  3. Essential Question (EQ): Explain the two steps needed to convert from a decimal number to a fraction. Explain the process of converting a fraction to a decimal. Reducing to Lowest Terms There are two different ways to reduce a fraction to lowest terms. 2. Known as the ________ method. ladder

  4. Essential Question (EQ): Explain the two steps needed to convert from a decimal number to a fraction. Explain the process of converting a fraction to a decimal. How can we use the Ladder method to reduce 24/60? 2 24 60 Divide out all the common factors down the left side. What number goes into both 24 and 60? Does any # besides 1 go into both 12 and 30? 2 12 30 How about 6 and 15? Anything else? 3 6 15 No? You’re done. 2 5

  5. The numbers on the bottom of the ladder are your simplified numerator and denominator. Essential Question (EQ): Explain the two steps needed to convert from a decimal number to a fraction. Explain the process of converting a fraction to a decimal. Which numbers in the ladder give you the simplified fraction? # # # # # # # # # # #
