UNIT 4 LESSON 10 REVIEW

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

EQUIVALENT FRACTIONS 5/11 7/25

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 x + = 7 2

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

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

IMPROPER FRACTION TO MIXED NUMBER 21/5 11/5

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

DECIMALS TO FRACTIONS

Order the numbers from least to greatest , and 0.7, 3535 = 0.60 Graph the numbers on a number line Write as decimals with the same number of places = = 0.70 Course 2 Comparing Rational Numbers

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

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

DIVIDING A FRACTION BY A FRACTION x Basically, in order to divide fractions we will have to multiply ÷ =

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

NOW, MULTIPLY AND SIMPLIFY = )8) 3 x

DIVIDING FRACTIONS – ANOTHER EXAMPLE = ÷ 2 Convert to improper fraction

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?
