Algebra 1 Section 1 1 The Real Numbers Youtube Openstax college algebra. The property states that, for every real number a, there is a unique number, called the multiplicative inverse (or reciprocal), denoted 1 a, that, when multiplied by the original number, results in the multiplicative identity, 1. a ⋅ 1 a = 1. for example, if a = − 2 3, the reciprocal, denoted 1 a, is − 3 2 because. The property states that for every real number a, there is a unique number, called the multiplicative inverse (or reciprocal), denoted 1 a, that, when multiplied by the original number, results in the multiplicative identity, 1. a ⋅ 1 a = 1. for example, if a = − 2 3, the reciprocal, denoted 1 a, is − 3 2. because. A b=b a. we can better see this relationship when using real numbers. (−2) 7 = 5 \text { and } 7 (−2)=5. similarly, the commutative property of multiplication states that numbers may be multiplied in any order without affecting the product. a\times b=b\times a. again, consider an example with real numbers.

We can also see that every natural number, whole number, and integer is a rational number with a denominator of 1. because they are fractions, any rational number can also be expressed in decimal form. any rational number can be represented as either: a terminating decimal: 15 8 = 1.875, or. a repeating decimal: 4 11 = 0.36363636 … = 0. 36 ―. Examples: • 1 2 is a rational number. • 0.75 is a rational number (3 4) • 1 is a rational number (1 1) • 2 is a rational number (2 1) • 2.12 is a rational number (212 100) • −6.6 is a rational number (−66 10) irrational numbers real numbers that cannot be written as a simple fraction. 1.5 is rational, but π is irrational.
