Once the matrix is created you can use the reciprocal key to get the inverse.
I hope you will not hold against me if I showed the whole porocess. (No reflexion on your or anybody's abilities to create a matrix. Just trying to be helpful to more people.)

values you will see at the bottom are exact fractions.

Thank you!
