There is an easy steps on how to convert a decimal into a fraction. First is you need to divide it by one(I will reduce it to 3 decimal places so that it would be easily be divided later, it goes 0.163/1). Next is you need to multiply both side by 10 until the decimal number would be gone(goes like this, 163/1000). Lastly simply fit until it became a simplified fraction. So the answer to it is (4/25)
