Lesson 5.5 Compare and Order Rational Numbers Wednesday, Oct 5 Lesson 5.5 Compare and Order Rational Numbers

Compare and Order Rational Numbers Objective: To understand how to compare and order all rational numbers.

Compare and Order Rational Numbers The number line can be used to compare and order all rational numbers.

Compare and Order Rational Numbers Rule #1- A negative number is always less than any positive number.

Compare and Order Rational Numbers Rule #2 – When comparing two fractions, use the “cross multiplication” method to convert the fractions to “like” denominators. Then just compare the numerators.

Compare and Order Rational Numbers Rule #3 – When comparing a decimal and a fraction, one form must be converted to the other. Either convert the fraction to a decimal or vice versa. Hint – Most of the time it is easiest to convert the fraction to a decimal.
