Compare and Order Rational NumbersCompare and Order Rational NumbersObjective: To understand how to compare and order all rational numbers.

Compare and Order Rational NumbersFill in with or = to make a true statement.-1.2 0.8

Compare and Order Rational NumbersFill in with or = to make a true statement.-1.2 < 0.8

Remember On a number line the number to the left is always less than the number to the right.

Compare and Order Rational NumbersFill in with or = to make a true statement.-1.4 -1.25

Compare and Order Rational NumbersFill in with or = to make a true statement.-1.4 < -1.25

Compare and Order Rational NumbersThe number line can be used to compare and order all rational numbers.

Compare and Order Rational NumbersRule #1- A negative number is always less than any positive number.

Hint If both integers have a negative sign, determine the answer without the signs then reverse it. Compare and Order Rational NumbersFill in with or = to make a true statement. -3 1

Do this on your own.

Compare and Order Rational NumbersFill in with or = to make a true statement. -3 < 1

Since - 3 is negative and 1 is positive, - 3 is less.

Compare and Order Rational NumbersFill in with or = to make a true statement. -3 - 4

Do this on your own.

Compare and Order Rational NumbersFill in with or = to make a true statement. -3 > - 4

Since 3 < 4, then - 3 > -4.

Compare and Order Rational NumbersRule #2 When comparing two fractions, use the cross multiplication method to convert the fractions to like denominators. Then just compare the numerators.

Compare and Order Rational NumbersRule #3 When comparing a decimal and a fraction, one form must be converted to the other. Either convert the fraction to a decimal or vice versa.

Hint Most of the time it is easiest to convert the fraction to a decimal. Compare and Order Rational NumbersFill in with or = to make a true statement.0.75

Do this on your own.

Do this on your own.

Compare and Order Rational NumbersFill in with or = to make a true statement.-0.51 > - 0.53

0.53 We can stop here, why? 15 ) 8.00 -75 50 -45

Compare and Order Rational NumbersCompare and Order Rational NumbersCompare and Order Rational Numbers Compare and Order Rational Numbers Compare and Order Rational NumbersCompare and Order Rational Numbers88When you order a set of numbers, make sure you use the original form of the number. Compare and Order Rational Numbers Determine whether the following statement is always, sometimes or never true. Give examples to justify your answer. If x and y are both greater than zero and x > y, then -x < -y.

Compare and Order Rational Numbers Determine whether the following statement is always, sometimes or never true. Give examples to justify your answer. If x and y are both greater than zero and x > y, then -x < -y. Always, the greater the number is, the farther away from zero. Therefore its opposite will also be farther from zero.

Compare and Order Rational Numbers Explain why 0.33 is less than 0.33.

Compare and Order Rational Numbers Explain why 0.33 is less than 0.33.

The thousandths place in the first decimal is 0. The thousandths place in the second decimal is a 3, so0.330 < .333

Compare and Order Rational Numbers Explain why -0.33 is greater than -0.33.

Compare and Order Rational Numbers Explain why -0.33 is greater than -0.33.

The thousandths place in the first decimal is 0. The thousandths place in the second decimal is a 3, so-0.330 > -0.333

Essential QuestionMrs. Plums science class is growing plants under different conditions. The table shows the difference from the average for some students plants. Order the differences from least to greatest.
