1. UNIT 4 LESSON 10 REVIEW

2. The Giant One is used to find equivalent fractions. It is used to reduce or simplify fractions. The giant one works because of the Identity Property. copyright©amberpasillas2010

3. EQUIVALENT FRACTIONS 5/11 7/25

4. HOW TO CHANGE A MIXED NUMBER TO AN IMPROPER FRACTION Multiply the whole number times the denominator. Add your answer to the numerator. Put your new number over the denominator. 4 1 2 x + = 7 2

5. MIXED NUMBER INTO IMPROPER FRACTION 2 2/3 5 2/7

6. CHANGE THIS IMPROPER FRACTION TO A MIXED NUMBER. 7 3 = 3 ) 7 2 r1 Put your remainder over the denominator. = 2 1 3

7. IMPROPER FRACTION TO MIXED NUMBER 21/5 11/5

8. Write.6 as a fraction.6 = Can be simplified to:.6 =

9. DECIMALS TO FRACTIONS.235.0014

10. Order the numbers from least to greatest. 3535 0.84, and 0.7, 3535 = 0.60 Graph the numbers on a number line. 0 0.2 0.4 0.6 0.8 1 0.84 Write as decimals with the same number of places. 0.84 = 0.84 0.7 = 0.70 Course 2 Comparing Rational Numbers

11. ORDERING RATIONAL NUMBERS 2/3, 1.25, 1 1/12. 1 5/6, 1.05

12. PERIMETER 3 3/8m 6 5/8m 5 1/8m P = 14 9/8 P = 15 1/8m 9/8 = 1 1/8

13. EXAMPLE 2/3 cm P = 2/3 cm

14. FIND THE AREA OF THESE RECTANGLES. 3 1/3 4 5/9

15. RECIPROCALS Reciprocals or multiplicative inverse are two numbers whose product is 1. For example ¾ and 4/3 are reciprocals because (¾)(4/3) =1

16. RECIPROCALS What are the reciprocals of the following fractions 3/7 7/91 32/33 2 5/6 5

17. DIVIDING A FRACTION BY A FRACTION x 1 2 4 1 Basically, in order to divide fractions we will have to multiply. 1 2 1 4 ÷ =

18. DIVIDING FRACTIONS – AN EXAMPLE 2 9 3 4 = ÷ Since both are fractions, now you can Keep ( 1st fraction ), Change ( the operation to multiplication ), and Flip ( 2 nd Fraction )…

19. NOW, MULTIPLY AND SIMPLIFY 9 2 3 4 = 27 8 8)8) 3 x 24 3 3 8

20. DIVIDING FRACTIONS – ANOTHER EXAMPLE 2 8 1 3 = ÷ 2 Convert to improper fraction

21. 4/5 Y = 4

22. Reem divides the bread dough she makes into 6 pieces the weigh of each is 2 1/3 lb. How much dough did Reem make?
