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.

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.

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.

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.

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).

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.
