That makes no sense. What is the complete problem?

im trying to solve a number of equation for km and Vmax and at the moment they are all in 1/km and 1/Vmax form.
For example
1/Km is 75 and 1/Vmax is 0.03

yea, I know, looks bizarre to me also ... and I'm a physics teacher.

here's a shot in the dark ...

if 1/(km) = 75, then km = 1/75

if 1/v<sub>max</sub> = 0.03, then v<sub>max</sub> = 1/0.03 = 100/3

you know, it really would help if we knew what the original problem involved.

im doing a biochem assignment. they are results off a lineweaver-burk graph and the number you get off the graph is 1/km when what i need is the km.

thanks for your help
