How to round to the nearest tenth
Keep one digit after the decimal point and look at the second: if it is 5 or more, round the first digit up; otherwise leave it. Half-values round up.
Common mistake
Confusing tenths with tens. The tenths place is the first digit after the decimal (0.1); rounding to “tens” changes the whole-number tens digit instead.
