Name ways we can categorize people in the classroom

• Example: gender, eye color…etc.

Simplify.

2/3 + 4/9 =

4/10 – 2/5 =

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)

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
• 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
• 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
