• Compare and order decimals. • Inequality = a math sentence using < or > to show that two quantities are not equal. – Ex. 4. 15 > 2. 40 • Equivalent decimals = decimals that have the same value. – Ex. 0. 8 and. 80 8/10 or 8 out of 10 80/100 or 80 out of 100

Compare Decimals BASEBALL The table below lists the final winning percents for several American League baseball teams in a recent year. Use > or < to compare New York’s percent with Cleveland’s percent.

Compare Decimals Method 1 Use place value. New York: Cleveland: 0. 594 0. 562 First, line up the decimal points. Then, starting at the left, find the first place the digits differ. Compare the digits. Answer: Since 9 > 6, 0. 594 > 0. 562.

Compare Decimals Method 2 Use a number line. Numbers to the right are greater than numbers to the left. Since 0. 594 is to the right of 0. 562, 0. 594 > 0. 562. Answer: New York had the higher winning percentage.

EXAMS In Mr. Smith’s math class, 29. 65% of the students earned a grade of “A” at the end of the semester. In Mrs. Dempsey’s class, 29. 85% of the students earned a grade of “A” at the end of the semester. Use > or < to compare the percent in Mr. Smith’s class with the percent in Mrs. Dempsey’s class. A. 29. 65% < 29. 85% B. 29. 65% > 29. 85% 1. 2. A B

Order Decimals Order 25, 25. 1, 24. 36, and 25. 03 from least to greatest. First, line up the decimal points. Next, annex zeros so all numbers have the same final place value. Finally, compare and order using place value. 25 25. 00 24. 36 25. 10 25. 00 24. 36 25. 03 25. 10 Answer: The order from least to greatest is 24. 36, 25. 03, and 25. 1.
