0.98 We need to round off the number to the nearest tenth. First cut off the number after tenths place. i.e. 0.9 Look only the first digit you are cutting off. ignore other numbers. i.e. look digit 8. 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 8 so round up by adding 1 tenth to the part you are keeping. i.e. 0.9 + 0.1 = 1.0. So Answer is 1.0.
