Multiplicative inverse is for example x then its mutilpicative inverse is 1/x

thesmartone · Answer

because a number multiplied to its multiplicative inverse equals to 1..

thesmartone · Answer

So in your case teh multiplicative inverse is 9/5..

thesmartone · Answer

do you understand that part??

anonymous · Answer

yes i think so the multiplicative inverse 9/5
additive inverse 5/9?

thesmartone · Answer

additive inverse for example 5 its additive inverse is -5

thesmartone · Answer

because the number + additive inverse =0

thesmartone · Answer

so 5/9+ x=0
x=-5/9

thesmartone · Answer

not 5/9...

thesmartone · Answer

Do you understand why...

anonymous · Answer

oh....ok yeah beccause it's a negative the additive should be the opposite right?

thesmartone · Answer

The number plus the additive inverse has to equal to zero...

thesmartone · Answer
