How do you solve for the partial pressures in this problem?

Use PV=nRT, then convert it to P=MRT, (n/v = concentration = M) Then proceed to use the values given in concentrations to solve for the pressures individually. These are the partial pressures.

Convert each concentration to a partial pressure using PV=nRT. You are given n/V, R and T so you just need to solve for P.

I got 0.00192 atm, 0.0137 atm, and 0.0237 atm as my answers but they're aren't exactly any of the answer choices listed. Why would my answers be two decimal points off?
