Understanding Rounding to the Nearest Tenth
What is the Tenths Place?
The tenths place is the first digit after the decimal point. It represents one-tenth (1/10) of a whole unit. When rounding to the nearest tenth, we look at the hundredths place (second digit after decimal) to decide whether to round up or down.
