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.
