Basic math equation help.

In the equation

x = n / f

n is 1 kg m^-2 and f is 1 kg m^-1

What is x?

This is just confusing my poor brain, any help to understand would be much appreciated.

I put what I thought the answer was as x = 1 kg m^2 but I'm told the numerical value is correct but the unit is incorrect, am I being stupid here or am I missing something blatantly obvious?

Thanks for any help regarding this.

See the picture for an example of how to handle units in this case. You can think of most units as being a quantity multiplied by the number.

$\frac{kg}{m^2}/\frac{kg}{m}=\frac{1}{m}$ so $n/f=1/m$.
