LT 2.1 A One-sTep Equations - Fractions
  • Review Box
  • Mixed Number
  • 1 ½
  • It combines a regular number with a fraction
  • Improper Fraction
  • 3/2
  • Fractions where the top number (numerator) is bigger than the bottom number (denominator)
slide5

Cont. Review Box

  • Convert Mixed Number to an Improper Fraction
  • Multiply the denominator by the “regular” number
  • Add the numerator to step 1 or the multiplication (denominator x “regular” number)
  • Put answer in numerator
  • Keep the denominator
  • Example:
  • 1 ½ 2 x 1 = 2, 2 + 1 = 3 3/2
slide7

cont. review box

  • Convert Improper Fraction to a Mixed Number
  • Do long division
  • Divide the numerator by the
  • denominator
  • Your answer is the “regular”
  • number
  • The remainder is the numerator of the fraction, the denominator stays the same
  • Example:
  • 45/4

Fraction is division!

adding subtracting fractions with like denominators
Adding & Subtracting Fractions with like denominators
  • You ONLY add/subtract the numerators
  • The denominators stays the same
slide10

Adding & Subtracting Fractions with unlike denominators

  • You must have “common” (the same) denominators.
  • Once you have the same denominator, you can add/subtract the fractions.
  • You ONLY add/subtract the numerators
  • The denominators stays the same
