To round to the nearest tenth, you look to the number to the right of the tenths place (the first number after the decimal is the tenths place, and you are looking at the hundredths place). If that number is five or higher, the number after the decimal goes up by one (it is "rounded up"). If that number is four or less, the number after the decimal stays the same. No matter what happens to the number in the tenths place, the number in the hundredths place (and any numbers that might be after it) are "thrown out" and go away
