4. Comparison Symbols Less than Greater than Less than or equal to Greater than or equal to Remember, the alligator always wants to eat the bigger number!

5. Compare Some Which is greater? There are two ways… Get a common denominator Turn both into a decimal

6. Let’s give it a shot! Put the numbers in order from least to greatest Two techniques: either turn each fraction into a decimal get a common denominator and compare the numerators

7. Absolutely only one more thing… Absolute Value: the distance a number is from zero The positive version of x whether it started off as positive or negative
