The tenth's place in decimals is the first place to the right of the decimal point. The second place is the hundredth's place. The value of the number in the hundredth's place is the number which determines whether you round the value in the tenth's place up or down, which essentially means leaving the tenth's value as the number it is. Once you complete the rounding process, drop all the digits to the right of the tenth's place.

For example, in rounding the number 5.43 to the nearest tenth, find the first number to the right of the tenth's place. Because the three is less than five, the number rounded to the nearest tenth is 5.4

However, suppose the number is 5.99. Looking at the first number to the right of the tenth's place, you see a nine, so you must raise the value of the tenth's place up one. Since the number in the tenth's place is a nine, you must go to the next number to the left and raise it up one. The value of 5.99 to the nearest tenth is 6.0. Add the decimal point and the zero to show you are rounding to the nearest ten.
