  1. Please get out your homework, a pencil and your notes journal. Please be ready as soon as the bell rings. If you have any questions please put them on a Sticky note and put it on my desk by the computer.

  2. Equivalent Fractions • An equivalent fractions are fractions that represent the same value. • You can find equivalent fractions by multiplying or dividing the numerator and the denominator by the same number.

  3. Comparing and Ordering fractions • To compare and order fractions you need to find a common denominator. You find a common denominator by finding the LCM of the denominators you have and finding equivalent fractions with those denominators. • You then compare the numerators. • If you only have two or three fractions you can compare and order them by cross multiplication.

  4. Adding Fractions with Like Denominators. • To add fractions with like denominators you add the numerator and keep the denominator the same. • You simplify(reduce) the fraction if you can by dividing the numerator and the denominator by the same factor (number). • To add mixed numbers, you change the fractions to improper fractions and add the improper fractions the same way as you add regular fractions.

  5. Subtracting Fractions with Like Denominators. • To subtract fractions with like denominators you subtract the numerators and keep the denominator the same. • You simplify(reduce) the fraction if you can by dividing the numerator and the denominator by the same factor (number).

  6. Adding Fractions with UNLIKE denominators • To add fractions with different denominators you have to find a common denominator by finding the LCM of the denominators. Then you find equivalent fractions using the new denominator. • You then add the numerators and keep the denominator the same. • You simplify(reduce) the fraction if needed.

  7. Subtracting Fractions with UNLikeDenominators. • To subtract fractions with different denominators you have to find a common denominator by finding the LCM of the denominators. Then you find equivalent fractions using the new denominator. • You then subtract the numerators and keep the denominator the same. • You simplify(reduce) the fraction if needed.
