  1. Equivalent Fractions Fractions in Lowest Terms and Fractions in Higher Terms 4.5 – 4.6 Mrs. Christman

  2. Pizza

  3. Pizza 3/4 9/12 6/8

  4. Multiply by 1 • 5 x 1 = • 235 x 1 = • 2/3 x 1 = • a x 1 = 5 235 2/3 a

  5. What is 1?

  6. Fractions in the Higher Terms

  7. Raising Fractions • A man walks into the pizza store and orders a medium pizza. • The clerk asks “ Would you like that cut in 8 pieces or 6?” • The man replied “ Make it 6. I don’t think I can eat 8.”

  8. Raising Fractions • To raise fractions make the denominator larger. • Multiply numerator and denominator (top and bottom) of the fraction by the same number. • This is the same thing as multiplying by 1.

  9. Raising Fractions • Multiply numerator and denominator (top and bottom) of the fraction by the same number. • This is the same thing as multiplying by 1.

  10. Raising Fractions • Raise 3/8 to 56ths. • Multiply numerator and denominator (top and bottom) of the fraction by the same number.

  11. Raising Fractions • Raise 3/8 to 56ths. • Multiply numerator and denominator (top and bottom) of the fraction by the same number.

  12. Fractions in Lowest Terms • Opposite of raising. • Make the denominator smaller. • Find the greatest common factor (GCF) • Divide numerator and denominator by the GCF

  13. Reducing Fractions • Might take more than one step. • More than one way. • Divide numerator and denominator by the same number.

  14. Reducing Fractions • Divide numerator and denominator by the same number, GCF

  15. Reducing Fractions • Divide numerator and denominator by the same number.
