Section 2-7, “Comparing and Ordering Rational Numbers” A RATIONAL NUMBER i i i is a number that can be written as a fraction with an integer for its numerator and a nonzero integer for its denominator.

“Rational Numbers” Rational Numbers Integers Whole Numbers 0,1,2,3,4,5… 0,1,2,3,4,5… Integers Integers -3,-2,-1, 0,1,2,3… Rational Numbers Rational Numbers numbers that can numbers that can represented as a ratio or fraction Whole Numbers

“Comparing Fractions” Compare the fractions and. Same denominator, now compare numerators = = Therefore, 4/5 is greater 3/4. When two fractions have different denominators, write equivalent fractions with common denominators. Then compare the numerators.

Compare the Following Fractions < > <

“Comparing Decimals” 0.81 To compare decimals, line up the decimal points and compare the digits from left to right until you find the place where the digits are different is greater than 1, so 0.84 is greater than 0.81 Compare the fractions. Write is greater than 2, so 0.34 is greater than Compare the fractions. Write. ><

Order the Numbers from Least to Greatest , 0.7, 0.71, 0.70, Line up numbers by the decimal point Write all decimals in the same place value Place numbers in order from least to greatest
