1/[N2O] = 1/(1.75M) + (1.10E-3M^-1 S^-1)(1852s)

[N2O] = 0.383 M

I know I posted a similar question but I am having trouble with this one as well. Should I do 1/1.75 first and then add 1.10e-3 and then multiply by 1852?

So first I did multiplication (1.10e-3)(1852) and then divided 1/1.75 and then added and I cant get the answer.
