If there's a zero in the tenths place and your round down, keep the zero in your answer. For example, 4.03 rounded to the nearest tenth is 4.0. This gives people a better idea of the accuracy of your number. Just writing "4" isn't wrong, but it hides the fact that you were working with decimals. Rounding negative numbers is basically the same as rounding positive numbers. Follow the same process and always keep the minus sign in your answer. For example, -12.56 round to -12.6, and -400.333 rounds to -400.3. Be careful about using the phrases "round down" and "round up." If you look at a number line for negative numbers, you'll see that rounding -12.56 to -12.6 moves left, so that's "rounding down" even though you increased the tenth digit by 1. Don't get confused by super long numbers. The rules stay the same. Find the tenths place and figure out whether to round up or down. After rounding, all the numbers to the left of the tenths place will stay the same, and all the numbers to the right of the tenths place will disappear. Here are three examples:  7192403242401.29 rounds to 7192403242401.3 5.0620138424107 rounds to 5.1 9000.30001 rounds to 9000.3 Does the number end in the tenths place, with nothing further to the right? This number is already rounded to the nearest tenth, so you don't need to do anything here. Your textbook might be trying to trick you. For example, 1509.2 is already rounded to the nearest tenth.
