The r.m.s velocity of hydrogen is  times the r.m.s. velocity of nitrogen. If T is the temperature of the gas,

The difference of  and its reciprocal is

So here the concept of reciprocals and reciprocating the numbers is used. It is basically comparable to flipping the number on its side. Here we were given the numberand the difference between this number and its reciprocal is 105/304.
