2. 5 MinutesSpongePage 1 of Sponge Book Freda pays \$ 475 for each IPAD she purchases online plus a \$25.00 shipping and handling fee. CREATE an equation that will REPRESENT the total cost of the IPADS.

3. Answer • 475 (I) +25= C • The (I) represents the number of IPODS purchased and the (C ) represents the total amount paid. Take 2 minutes to consider: • If Freda were to purchase 3 IPADS what would the final cost be?

4. 475 (3)+25=\$1450.00

6. The REAL NUMBER SYSTEM Ms. A Cherry-Davis Mrs. Vaughan

7. Two Kinds of Real Numbers • Rational Numbers • Irrational Numbers

8. Two Kinds of Real Numbers • Rational Numbers • Irrational Numbers

9. Rational Numbers • A rational number is a number that can be written as a fraction and terminates or repeats

10. 16 1/2 3.56 -8 1.3333… - 3/4 Examples of Rational Numbers

11. Irrational Numbers • An irrational number cannot be written as a fraction

12. Square roots of non-perfect “squares” Pi Examples of Irrational Numbers 17

13. Integers One of the subsets of rational numbers

14. What are integers? • Integers are the whole numbers and their opposites. • Examples of integers are 6 -12 0 186 -934

15. Integers are rational numbers because they can be written as fraction with 1 as the denominator.

16. Natural Numbers • Natural numbers are the set of counting numbers. {1, 2, 3,…}

17. Whole Numbers • Whole numbers are the set of numbers that include 0 plus the set of natural numbers. {0, 1, 2, 3, 4, 5,…}

18. Venn Diagram of the Real Number System Rational Numbers Irrational Numbers

19. Use the venn diagram to classify each number • Classify all the following numbers as natural, whole, integer, rational, or irrational. List all that apply. • 117 • 0 • -12.64039… • -½ • 6.36 • -3

20. Answer Rational Numbers Irrational Numbers Integers 6.36 Whole Numbers -12.64039… Natural Numbers -3 0 117

21. Solution • Now that all the numbers are placed where they belong in the Venn diagram, you can classify each number: • 117 is a natural number (Counting Number), a whole number, an integer, and a rational number. • is a rational number. ANY NUMBER THAT CAN BE WRITTEN AS A FRACTION • 0 is a whole number, an integer, and a rational number. • -12.64039… is an irrational number. • -3 is an integer and a rational number. • 6.36 is a rational number. • is an irrational number. • is a rational number.
