  1. MJ3 Ch 2.3.2 – Simplifying Fractions (pg. 611)

  2. Bellwork • Please take out your assignment from yesterday and leave it on your desk so that I can check it. • Find the GCF • 6, 18, 40 • 17, 34

  3. Before we begin… • Please take out your notebook and get ready to work… • Yesterday we reviewed how to get the GCF of two or more numbers • Today we will use what we learned about the GCF to simplify fractions….

  4. Objective • Students will simplify fractions using the GCF

  5. Simplifying Fractions • When a rational number is represented by a fraction it is often expressed in simplest form • A fraction is in its simplest form when the GCF of the numerator and denominator is 1 • There are 2 methods to simplify fractions using the GCF • Divide by the GCF • Prime factorization of the numerator and denominator

  6. Dividing by GCF • Demonstrate on board using 30/45

  7. Using Prime Factorization • Demonstrate on board using 30/45

  8. Comments • These are 2 of several strategies that you can use to simplify fractions… • Personally, I do not use either of these methods as I know my multiplication tables…You will make your life easier if you know your multiplication tables by rote memory… • Ultimately, you are required to know how to simplify fractions…you may use whichever method you are most comfortable with…

  9. Your Turn • In the notes section of your notebook simplify the following using either of the methods we discussed today… • 15/30 • 8/48 • 12/36

  10. Assignment • Text p. 611 # 1 - 38
