Answer 14

\[\Large\rm 3.87655=\frac{3.87655}{1}\]Multiply the top and bottom of this fraction by 100,000.
This will effectively move the decimal 5 places in the numerator.\[\Large\rm =\frac{387,655}{100,000}\]

A rational number is one which can be written as the ratio of `integers`.
Example:\[\Large\rm \frac{5}{2}\]5 over 2 is rational because 5 and 2 are integers.


So for our problem, see how we were able to write it in that form?
integer over integer.
