What is a rational number? A rational number is any number that can be written in fraction form,, where a and b are integers and b ≠ 0 For Example: -4 5 .25 1.5 .8888 Any decimal that is terminating or repeating How can these numbers be written as fractions and decimals?
What is an integer? An integer is a whole number and its opposite For example: -2, -1, 0, 1, 2 No fractions and no decimals

What is a whole number? Whole numbers are simply the numbers 0, 1, 2, 3, 4, and so on Counting numbers are whole numbers except without zero, because you cant count zero There are no negatives, no fractions and no decimals
