2
7.1 A – Comparing Integers and Positive Rational Numbers

3
Rational Numbers - Numbers that can be written in the form of a fraction. EX: The number 9 as a fraction is 9/1 The mixed number 2 ¼ as a fraction is 9/4 The mixed decimal 2.25 as a fraction is 9/4 The decimal 9.00 as a fraction is 9/1

4
Comparing Rational Numbers *** To compare rational numbers first convert them to the SAME FORM, either fraction or decimal. Fractions (w/ same denominator): 6 8 9 9 Same

5
6/9 8/9

6
Fractions (w/ different denominators) 2 3 3 4different Since the denominators are different, find the least common multiple for 3 & 4 Multiples of 3: 3, 6, 9, 12, 15 Multiples of 4: 4, 8, 12, 16, 20 Make 12 the denominator: 2/3= 8/12 & ¾= 9/12

7
Comparing Decimals Line up your decimals and begin with the number furthest to the left EX:5.862 3.741 *if numbers are the same move to the next number to the right EX:4.873-or-13.789 4.92612.987

8
Converting Fraction to Decimals to % Fraction to decimal: ¾ = ¾ =.75 Decimal to %:.75 = 75% % to Decimal:48% =.48 Decimal to fraction:.48 = 48/100 (reduced 12/25)

9
Which is Greater? 11.5or 11 2/3
