0.091

Work Step by Step

0.0905 We need to round off the number to the nearest thousandth. First cut off the number after thousandths place. i.e. 0.090. Look only the first digit you are cutting off. ignore other numbers. i.e. look digit 5. If the first digit you are cutting off is 5 or more, round up the part of the number you are keeping. here it is 5 so round up by adding 1 thousandth to the part you are keeping. i.e. 0.090 + 0.001 = 0.091 So Answer is 0.091.
