    Ein Kuchen wird an drei Kinder verteilt.

    Max erhält 13\gdef\cloze#1{\colorbox{dedede}{\color{transparent}{\large{$\displaystyle #1$}}}} \frac{1}{3} vom Kuchen, Franz erhält 721\gdef\cloze#1{\colorbox{dedede}{\color{transparent}{\large{$\displaystyle #1$}}}} \frac{7}{21} vom Kuchen, Julian wünscht sich 39\gdef\cloze#1{\colorbox{dedede}{\color{transparent}{\large{$\displaystyle #1$}}}} \frac{3}{9} vom Kuchen.
    • Kann der Wunsch von Julian erfüllt werden?
    • Bleibt von dem Kuchen noch etwas übrig und wenn ja wie viel?
