The numbers are given in <em>scientific notation</em>.
Let a number be
and another be
, when we divide, we will follow the rule shown below:

Now, we use the information given to find the ratio:

This means we can find the number by taking 4 decimal places to the right, so that would becomes:

The approximate ratio is 1833 [mass of proton is around 1833 times heavier than mass of electron]
