Deutsch — Fractions and arithmetic

In German, fractions such as ein Drittel or anderthalb, decimals written with a comma (drei Komma fünf), and calculations read aloud with plus, minus, mal and geteilt durch all follow clear, regular patterns.

How it works

✓ Rule

Fractions add -tel to the number (ein Drittel, ein Viertel) and -stel from twenty upward (ein Zwanzigstel); the numerator stays an ordinary number: zwei Drittel. Special forms are ein halb (½) and anderthalb (1½). Decimals use a comma: 3,5 is read drei Komma fünf. Operations are read with plus, minus, mal and geteilt durch, and the result is introduced by ist: drei plus vier ist sieben. A percentage is Prozent: zwanzig Prozent.

Good to know

⚠ Note

Watch the separators: German uses a comma for decimals and a point (or a space) for thousands, so 1.000,50 means one thousand and fifty hundredths — the reverse of English. Fraction words like Drittel are neuter, capitalized nouns (ein Drittel), whereas ein halb and anderthalb are not inflected.
