femtesdel

Femtesdel is a term used to denote one fifth of a whole. It represents a fifth share, equivalent to the fraction 1/5, the decimal 0.2, or 20 percent. The form appears in some Scandinavian language traditions, where femte means fifth and del means part. In contemporary Swedish, the standard term for one fifth is femtedel, and femtesdel may be found in older texts, dialectal usage, or cross-linguistic contexts.

The concept of a femtesdel is used whenever a quantity is divided into five equal parts. This applies to arithmetic problems, measurements, and divisions of property or goods. For example, cutting a cake into five equal portions yields five femttesdelar; taking one portion corresponds to one femtesdel. In education, femtesdel serves to illustrate fractions, proportions, and their decimal representations.

Historically, legal or land documents may mention femtesdel to describe a share or entitlement among heirs or co-owners, though spelling and terminology vary by region and era. The term is closely related to other fractional concepts such as halves and quarters, providing a basic building block for understanding parts of a whole. See also fractions, one fifth, 1/5.
