The answer will be less than 1. When you multiply any digits
            by the digit 1 you repeat those digits.
            example  456 x 1 = 456  Multiply any term by 1 and you end
            up with what you started with.   example   abr x 1 = abr
            So the answer for 6.3 x .1 must contain 63 in the original
            order and you determine where the decimal point goes.
            6.3 x .1 = 0.63  return

            

            There are 2 decimal places in the problem .3 and .1 Therefore 

            the answer must have 2 decimal places. Hence 0.63.
