Hi, 
Let x and y represnt the ten and unit digits of the original number.
Note: .625 = 5/8
When the digits of a two-digit number are reversed, the result is 
another two-digit number that is 62.5% smaller than the original number
62.5% smaller or 3/8 of original number
 10y + x = (3/8)(10x+y)
  80y + 8x = 30x + 3y
     77y = 22x
       7/2 = x/y
Original number is {{{72}}}

 27 = 3/8(72)
