How to find rational numbers between two given rational numbers? Find out three rational numbers lying between 3 and 4. Introduction of Rational Numbers. What is Rational Numbers? Is Zero a Rational Number? Is Every Rational Number an Integer?

Know what a set and an element are. Indicate if something is an element or is not an element of a set, using the appropriate notation. Tell if one set is a subset of another set. Read or write out a set in either roster form or set builder form. Know what the empty set is and how to notate it. Identify what numbers belong to the set of natural numbers, whole numbers, integers, rational numbers, irrational numbers, and real numbers. Find the absolute value of a number.

In this chapter, we'll make sure your skills are firmly set. We'll take another look at the kinds of numbers we have worked with in all previous chapters. We'll work.

We have already described numbers as counting numbers, whole numbers, and integers. Do you remember what the difference is among these types of numbers? What type of numbers would you get if you started with all the integers and then included all the fractions? The numbers you would have form the set of rational numbers. A rational number is a number that can be written as a ratio of two integers. We need to look at all the numbers we have used so far and verify that they are rational. The definition of rational numbers tells us that all fractions are rational.

You have completed the first six chapters of this book! It's time to take stock of what you have done so far in this course and think about what is ahead. You have learned how to add, subtract, multiply, and divide whole numbers, fractions, integers, and decimals. You have become familiar with the language and symbols of algebra, and have simplified and evaluated algebraic expressions. You have solved many different types of applications. You have established a good solid foundation that you need so you can be successful in algebra.

Math Dr. Math Home What is an integer? It is often useful to think of the integers as points along a 'number line', like this: Note that zero is neither positive nor negative. About integers The terms even and odd only apply to integers; 2. Zero, on the other hand, is even since it is 2 times some integer: it's 2 times 0. To check whether a number is odd, see whether it's one more than some even number: 7 is odd since it's one more than 6, which is even. Again, this lets us talk about whether negative numbers are even and odd: -9 is odd since it's one more than , which is even.
