  1. Warm Up Answer following questions: • What determines a plane? • 2) Can the line m and the point A determine a plane? Explain. A C B m

  2. Choose any 2 points named B and C on the line m. Postulate says that 2 points determine only 1 line. So line m is exactly the same as line BC. A, B, and C are noncollinear. Another postulate says that 3 noncollinear determines only 1 plane. Point A and the line m determine only a plane. Warm Up A C B m

  3. Mixed Fraction Addition

  4. Let’s do some review work before we begin. What is proper fraction? fraction whose numerator is smaller then the denominator What is improper fraction? fraction whose numerator is larger or equal than to its denominator What are mixed numbers? sum of a whole number and a proper fraction

  5. Method 1 Change the mixed number into an improper fraction Method 2

  6. How else can I add the mixed numbers? +

  7. Method 1 Add Mixed Numbers

  8. Method 1 Add Mixed Numbers

  9. Step 1 Add the whole number parts separately Step 2 Add the fraction separately. If the sum is an improper fraction, change it to mixed number and add the whole number parts again. Procedure for Method 1

  10. Method 2 Add Mixed Numbers

  11. Step 1 Find the LCD Step 2 Add the fraction separately. If the sum is an improper fraction, change it to mixed number and add the whole number parts again. Procedure for Method 2

  12. What is the LCD? Method 3 Add Mixed Numbers

  13. Step 1 Change mixed numbers to improper fraction. Step 2 Add improper fractions and simplify the answers. Procedure for Method 3

  14. Let’s Practice!
