**Fraction Multiplication**And Cancelation**Fraction Multiplication**• Here are some fraction multiplication problems • Can you tell how to multiply fraction from these examples?**Multiplication**• Multiply numerator by numerator • And denominator by denominator**Try some.**• Multiply the following:**Answers**• Multiply the following:**Mixed Numbers**• Because of the order of operations, • Mixed numbers cannot be multiplied as is • Change mixed numbers to improper fractions, then multiply.**Try some**• Change any whole or mixed numbers to improper. • Multiply straight across. • Simplify answers**Answers**• Change any whole or mixed numbers to improper. • Multiply straight across. • Simplify answers**Cancelling**Reduce before you multiply**Canceling**• Reducing before mutiplying is called canceling. • ICK! Instead think the following in your head.**Canceling on paper**• Rules: One factor from any numerator cancels with like factor from the denominator.**Try one**• Say “--- goes into ____ this many times.” • As you cross each number out and write what is left after canceling above the number.**Answer**• Say “--- goes into ____ this many times.” • As you cross each number out and write what is left after canceling above the number.**Try one more**• Make whole and mixed numbers improper • Cancel if you can • Multiply Numerators and denominators straight across. • Simplify**Answer**• Make whole and mixed numbers improper • Cancel if you can • Multiply Numerators and denominators straight across. • Simplify
