TX PACT 700 Essential Academic Skills MathReal Numbers - correct answer Numbers that have a specific value. Can be rational or irrational. Includes interger, whole, and natural numbers. Rational Numbers - correct answer Any number that can be expressed as a fraction or decimal form and be graphed on a number line Mixed numbers - correct answer a number that is made up of a whole number and a fraction Decimals - correct answer a number that uses place value and decimal points to show values less than one, such as tenths, hundreths, etc. Natural Numbers - correct answer real numbers that can be pointed to in nature, such as one tree, two people, three dogs. start at 1. Whole numbers - correct answer set of natural numbers, and zero. integers - correct answer positive and negative counting numbers irrational numbers - correct answer Numbers that cannot be expressed as a ratio of two integers.
