  1. 1/2 3/4 0.54 8% Rational NumbersA PowerPoint for 6th grade. -9 MCC6.NS.6.c: Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane.

  2. Rational Numbers Rational means “written as a ratio.” A ratio is the comparison of two quantities using division. Definition: Any positive or negative number that can be written as a ratio of two integers, where the denominator is not equal to zero.

  3. These numbers are all examples of rational numbers: 5/8 0.46 -9 3.33 25 10%

  4. Rational numbers have opposites, too! For example: 2/3 and -2/3 are opposites. -5.10 and 5.10 are also opposites.

  5. Find the opposites for the rational numbers on this number line:

  6. Explain why -2/3, 6 and 0.4 are rational numbers. • Ask, can I write these numbers in the form a/b? • The number 2/3 is written in the form a/b. • The number 6 can be written as 6/1 which is in the form a/b. • The number 0.4 can be written as 4/10 which is in the form a/b. The numbers 2/3, 6 and 0.4 are rational numbers because each can be written in the form a/b.

  7. Is this a rational number?
