0.178
to make the decimal to the fraction, you need to move the decimal to the right to the end. to go to the end, you need to move three times, so the denominator is 1000 because it's with the three zeros and you moved three times to reach to the end of the right.
so if you're changing it to the fraction, it would be 178/1000. if you simplify it, then it would be
178/1000 ÷2 on the both side = 89/500
the answer is 89/500
