Zero is the additive identity for rational numbers. Adding zero to any Additive Identity rational number results in a sum identical to the original rational number. For any rational number 0+ = For example, 0+ 4.375 = 4.375. a, a a. Subtracting a number is the same as ___________________________________________ Subtract: 6 8 = 6 + -8 – -5 9 = -5 + -9 – () = – -1.2 (-1.3) – Evaluate for the given values. a b – = -3 and = 2 b) = 4.2 and = -6.5 a b a b 3.2/3.3 Multiplying & Dividing Rational Numbers
