Real numbers symbol.

Answer: − 5 3. Two real numbers whose product is 1 are called reciprocals67. Therefore, a b and b a are reciprocals because a b ⋅ b a = ab ab = 1. For example, 2 3 ⋅ 3 2 = 6 6 = 1. Because their product is 1, 2 3 and 3 2 are reciprocals. Some other reciprocals are listed below: 5 8 and 8 5 7 and 1 7 − 4 5 and − 5 4.
