100 drittel = 3 %

$${\frac{{\mathtt{100}}}{{\mathtt{3}}}} = {\mathtt{33.333\: \!333\: \!333\: \!333\: \!333\: \!3}}$$    =3333,33333 %

$${\frac{{\mathtt{3}}}{{\mathtt{100}}}} = {\mathtt{0.03}}$$   = 3 %

Wenn der Nenner = 100 ist, darfst du den Zähler als  % schreiben.

Beispiel:        $${\frac{{\mathtt{25.5}}}{{\mathtt{100}}}} = {\frac{{\mathtt{51}}}{{\mathtt{200}}}} = {\mathtt{0.255}}$$       = 25,5  %
