Chapter Two: I Rational Numbers

Comparing and Ordering So first, you need to be able to change everything to decimals Then you just line’em up and compare!

Comparing Place <, >, or = between the two rational numbers

Ordering Order each set of numbers from least to greatest

Multiplying and Dividing Rationals Remember: the calculator is your friend. If you give it the correct information, it will give you the correct answer. This is all about how you put the numbers into the calculator. Decimals go in normal Fractions ALWAYS need parentheses.
