0.714
Step-by-step explanation:
5/7 = 0.7143 (4 decimal place)
To round to the nearest thousandth, we count the numbers after the point and stop at the 3rd number. Then we round the number after it (fourth number) and add to the 3rd number.
If the fourth number is 5 0r more, we round to 1. If less than 5, we round to zero
In this case, the fourth number after the decimal point is 3. Since it is less than 5, we round to zero.
5/7 to the nearest thousandth = 0.714
