Best ResponseYou've already chosen the best response.1Do you know what additive and multiplicative inverse means? We can start there...

Best ResponseYou've already chosen the best response.0I know what it means a little bit but not much. We just started this in our Algerba II

Best ResponseYou've already chosen the best response.1Additive inverse is simply the number that when added to the other number equals 0. So \[1.25+? = 0\]

Best ResponseYou've already chosen the best response.025 + 0 = 0? Is thar right?

Best ResponseYou've already chosen the best response.1First, let me clear something up: "3A. 1.25" So the problem is 3A and the value given is 1.25 right?

Best ResponseYou've already chosen the best response.1Ok...so what could you add to 1.25 which would result in a value of 0?

Best ResponseYou've already chosen the best response.1Since 1.25 is positive...you should see that you must add a negative number to make it 0. Therefore, the answer would be 1.25:\[1.25+(1.25)=0\]That's a true equation.

Best ResponseYou've already chosen the best response.0Right so it would be a 1.25 as a answer?

Best ResponseYou've already chosen the best response.0Alright so basically just switching a positve to a negative answer.

Best ResponseYou've already chosen the best response.1Maybe... If you're original number was 1.25...the additive inverse would actually be +1.25

Best ResponseYou've already chosen the best response.1If you're ok with everything above...we can discuss multiplicative inverses

Best ResponseYou've already chosen the best response.0Yeah thats alright so for 3A it would be 1.25?

Best ResponseYou've already chosen the best response.1Yes, that's additive inverse answer.

Best ResponseYou've already chosen the best response.1You still need to do the multiplicative inverse also. Multiplicative inverse is simply defined as the number that when multiplied times the original number result in an answer of 1. In essence, it's going to be the reciprocal of the original value. \[(1.25)(\frac{1}{1.25})=1\]So the multiplicative inverse of 1.25 is 1/1.25. You could also express this (as well as the additive inverse as a fraction which may be what your teacher wants:\[1.25=\frac{5}{4}\]So the additive inverse would be :\[\frac{5}{4}\] and the multiplicative inverse would be \[\frac{4}{5}\]
