Final answer:
To express (3)/(8) in decimal form, divide 3 by 8 and then round to the nearest thousandth.
Step-by-step explanation:
To express (3)/(8) in decimal form, we divide 3 by 8. In this case, 3 divided by 8 is equal to 0.375. Since we need to round to the nearest thousandth, we look at the digit in the thousandths place, which is 5. Since 5 is greater than 5, we round up the previous digit to get 0.376.
