  1. Solving Equations by Multiplying and Dividing Decimals 3.6

  2. Review: Multiplying Decimals Steps 1.Multiply 2.Count the amount of decimal places 3.Apply the decimal places to the product Example: (2.01)(0.04)

  3. Review: Dividing Decimals Steps: • The move over any decimal places in the divisor • Move the same amount of decimal places to the dividend • Bring the decimal up • Divide Example: 0.2816÷6.4

  4. MPE • You can multiply or divide the same number to both sides of the equation to solve.

  5. How to know when to multiply or divide? • Do the opposite operation of what is being done to the variable
