Use Base 10 notation to write decimal fractions - tenths, hundredths and thousandths. What's 138/1,000 written as a decimal number? 138/1,000 = 100/1,000 + 30/1,000 + 8/1,000 = 1/10 + 3/100 + 8/1,000, so write 1 in the tenths place, 3 in the hundredths places, and 8 in the thousandths place. 138/1,000 = .138 = 0.138.
