Understand that the problem asks for the relative mass of an electron compared to a proton, where the proton's mass is taken as 1 unit.
Recall that the proton is much heavier than the electron; the electron's mass is significantly smaller in comparison.
Use the known approximate mass ratio: the mass of an electron is about 1/1836 the mass of a proton.
Express this ratio mathematically as \(\frac{1}{1836}\), indicating the electron's mass relative to the proton's mass of 1.
Conclude that the relative mass of the electron compared to the proton is approximately \(\frac{1}{1836}\).
