tenths

Tenths are one of ten equal parts of a whole. In decimal notation, the tenths place is the first digit to the right of the decimal point and represents tenths of a unit. A tenth equals 1/10, so ten tenths make up one whole unit.

In decimal terms, 0.1 is one tenth, 0.2 is two tenths, and so on up to 0.9, which is nine tenths. When a number has a tenths digit, it indicates how many tenths are present in addition to the whole part. For example, 3.4 contains four tenths (0.4), while 7.89 contains eight tenths (0.8) and seven hundredths (0.09) as the next decimal places.

Tenths are closely related to fractions. The fraction 1/10 equals 0.1, and 2/10 equals 0.2, which simplifies to 1/5. Ten tenths equal one whole unit. In percentages, 0.1 corresponds to 10%.

Tenths are used in measurements, money, and various calculations in the decimal system. They enable expressing parts of a unit and performing arithmetic with precision smaller than one. In everyday terms, estimating to the tenths can convey a useful level of detail without going to hundredths.
