    Clearing Fractions Clearing Fractions Presentation Transcript

      • Goal: To solve an equation with fractions by first clearing the fractions.
    •  
      • Anytime you see Fractions in the equation multiply every term of your equation by the LCD.
      • LCD : Least Common Denominator
      • How do you find it? - Take all the denominators and take the Least Common Multiple
      • Least Common Multiple is the number that all the numbers could be multiplied by another number to get.
      • I look for the largest denominator and see if it is multiple by the other denominators
      • If it is multiple by the rest of the denominators then I am done 
      • If its not a multiple of the denominators then I multiply my largest denominator by 2 or 3 and keep doing the process until I find a number that is a multiple of all denominators
      • Multiply both sides to clear fractions and decimals, if necessary
      • Distribute.
      • Collect like terms on same side.
      • Move variables to same side of equation with the APE
      • Move the numbers (constants) to the other side of the equation with the APE
      • Use the MPE to solve for the variable
    •  
    • (2/3x) (6/1) +(1/2x) (6/1) = (5/6) (6/1) + (2x)( 6) (12x /3) + (6x /2) = (30/6) + (12x)
    • LCD = 4
    • Write the equivalent equation 1 1 1 1
      • - Subtract x from both sides to get the variables on the same side
      • Divide by 2 to solve for x
      • X=4
      x +8 =3x -x -x 8= 2x 2 2 4=x
      • (1g/3) + (2/5) = (3/2) - 2g
      • What is the LCD?
      • 30
    • Write the equivalent equation 10 1 6 1 15 1
    • +60 g +60 g - Add 60g to both sides to get the variables on the same side 70 g + 12 = 45 - Subtract 12 from both sides to get the numbers on the same side -12 -12 70 g = 33 - Divide both sides by 70 to solve for g 70 70 g= 33/70
