Title: Simplifying Fractions


1
Simplifying Fractions
  • Positive and Negative Fractions

2
Introduction
  • A fraction is a ratio that compares two numbers
    (a/b).
  • The first number, a, is called a numerator.
  • The second number, b, is called a denominator.

3
Process
  • To simplify fractions, first you must find a
    common factor.
  • Second, you must divide your fraction by the
    common factor, remembering to divide both the
    numerator and denominator by the same number.
  • Third, ensure that similar signs become a
    positive fraction.

4
Example 1
  • Simplify 25/35.
  • Find a common factor 5
  • Simplified Fraction 5/7

5
Example 2
  • Simplify -12/-32
  • Find a common factor 4
  • Simplified Fraction -3/-8
  • Adjust for similar signs 3/8

6
Example 3
  • Simplify -6/24
  • Find a common factor 6
  • Simplified Fraction -1/4

7
Conclusion
  • You cannot simplify fractions unless you have
    obtained a common factor, and divided both the
    numerator and denominator by the common factor.
