Divide Fractions 6-5 MULTIPLY FRACTIONS

NOTES: Divide Fractions with Models means how many ’s are in ? So, I have 4 groups of 2! Let’s try a fraction: So, I have 8 groups of ½! 6-5 MULTIPLY FRACTIONS

NOTES: Dividing Fractions VOCAB: The product of a fraction and its reciprocal (or multiplicative inverse) is 1. …To make a reciprocal, flip the fraction upside down! Rewrite in fraction form – Turn mixed #’s & whole #’s into improper fractions! 2. Multiply by the reciprocal. **Keep It – Change It – Flip It Method 3. As always…SIMPLIFY! DO NOT Have to FIND COMMON DENOMINATORS! 6-7 DIVIDE FRACTIONS

NOTES: Dividing Fractions When Dividing Fractions Don't be Shy Flip the 2nd And Multiply! 6-7 DIVIDE FRACTIONS

KCF: (Keep, Change, Flip) Step 1: Step 2: Step 3 Step 4 KCF: (Keep, Change, Flip) Step 1: Step 2: Step 3 Step 4 Simplify (reduce) and/or Convert to a mixed number Convert any mixed numbers or whole numbers to improper fractions. Multiply the fractions K =Keep the first number the same. C = Change the division symbol to a multiplication symbol. F= Flip the second number (to use the reciprocal)
