Look to the last number in the decimal; the 5 is in the thousandths place. This means we put the given decimal number 185 over 1000.
Example: If you were given 0.52, it would be converted to 52/100 (the last digit is in the hundredths place so the decimal numbers 52 are placed over 100) and then simplified.
0.185 = 185/1000
= 185/1000
simplify by 5
= 37/200
ANSWER: 37/200 is the fraction conversion of 0.185
Hope this helps! :)
