Question

what's the multiplicative inverse of -1 9/28

Answer 1

Using the number -1 9/28, demonstrate the Multiplicative Inverse Property
For any number A, the Multiplicative Inverse Property states:
A*(1/A)=1
Using our number that we entered of -1 9/28, we need to know if:
-1 9/28 * (1/-1 9/28) =1
Evaluating, we get 1=1
Since 1=1, we have proven the Multiplicative Inverse Property using the number -1 9/28.
