1 Operations and Rational Numbers (Fractions)
Chapter Page 119 Operations and Rational Numbers (Fractions) You make use your calculator

2 or Lesson 3.1 Page 123 Writing fractions as decimals
divide Write 7/8 as a decimal 0.875 or . 875

3 Write each fraction as a decimal 1a. 4/5 1b. 3/16
.8 .1875

4 1/6 = = .16 Decimal and Bar Notation .35 12.68

5 5/12 = = .416 -2/11 = = - .18 - 5/6 = 7/9 =

6 Page 124 Study Concept Summary Chart
It is helpful to memorize these fraction-decimals equivalents 1/2 = /3 = /4 = /5 = /10 = /100 = .01 2/3 = /4 = /5 = /5 = /5 = /6 = .83

7 < > = Page 125 Compare fractions and decimals Example 4 STUDY!
Draw a number line if needed. The number on the right is larger 1/ < > = Change the fraction to a decimal to make the sentence true 1/4 = .25 .25 is greater than .20 so 1/4 > .2

8 - 5/ /9 change to decimal graph number line if needed
