Multiplicative inverse is a no. which gives 1 when the given no. is multiplied by it. For example: 2 * 1/2 1 (therefore 1/2 is the multiplicative inverse of 2) Your Question: 2/3 * 3/2 1. Therefore 3/2 is the multiplicative inverse 2/3. Ans. 3/2. Additive inverse is no. which gives 0 when the given no is added with it. For example: 2 + (-2) 0 (therefore -2 is the additive inverse of 2). Your Question: a/4 + (-a/4) 0 Therefore -a/4 is the additive inverse a/4 Ans. -a/4
Well the 2/3 is changed to -2/3 i don't know about the other one
