Writing 0.374 as a Fraction

Convert the decimal 0.3740.374 to a simplified fraction using the decimal-to-fraction procedure:

  1. Find the place value of the last digit: The digits after the decimal point are 33 (tenths), 77 (hundredths), and 44 (thousandths). The rightmost digit 44 is in the thousandths place, so the denominator is 1,0001{,}000.
  2. Write the fraction: The digits to the right of the decimal point form the whole number 374374, giving 3741,000\frac{374}{1{,}000}.
  3. Simplify: Factor the numerator and denominator to find common factors: 3741,000=21872500\frac{374}{1{,}000} = \frac{2 \cdot 187}{2 \cdot 500}. Divide out the common factor of 22: 187500\frac{187}{500}.

Therefore, 0.374=1875000.374 = \frac{187}{500}. Notice that the number of zeros in the original denominator (1,0001{,}000 has three zeros) matches the number of decimal places in 0.3740.374 (three decimal places).
