Name ways we can categorize people in the classroom

  • Example: gender, eye color…etc.



Name ways we can categorize people in the classroom example gender eye color etc

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)


Name ways we can categorize people in the classroom example gender eye color etc

  • 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

  • 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

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


How can you find the common denominator how do you change a fraction to have a new denominator
