Look for the decimal in a number. If there is no decimal written, assume the decimal to be located to the right of the last digit of the number.
Identify the number immediately to the right of the decimal. This is the digit in the tenths place. If there is no decimal, the digit in the tenths place would be zero. Otherwise, you might have an example such as 3.45, in which the number 4 represents the tenths place.
Interpret numbers in the tenths place as a fraction of a whole number. For example, if you have the number 2.7, 7 is in the tenths place. You also could state the number as 2 7/10 or "two and seven-tenths."
Round the digit in the tenths place if necessary by looking to the digit to its right This is the hundredths position. If the digit in the hundredths position is between zero and four, keep the tenths digit the same. If the digit in the hundredths position is between 5 and 9, round the tenths digit up to the next number. For example, 8.3 (assume a zero for the hundredths place in this figure) or 8.34 would both be rounded to 8.3. On the other hand, 8.36 would be rounded to 8.4.
