Hej!
[tex]2 \frac{7}{15} - 1 \frac{1}{5} = 2 \frac{7}{15} - 1 \frac{3}{15} = 1 \frac{4}{15} \\ \\ \frac{4}{9} \div \frac{2}{27} = \frac{4}{9} \times \frac{27}{2} = 2 \times 3 = 6[/tex]

[tex]2\frac{7}{15} - 1\frac{1}{5} = \frac{37}{15} - \frac{6}{5} = \frac{37}{15} - \frac{18}{15} = \frac{19}{15} = 1\frac{4}{15}[/tex]
[tex]\frac{4}{9} : \frac{2}{27} = \frac{4}{9} * \frac{27}{2} = \frac{2}{1} * \frac{3}{1} = \frac{6}{1} = 6[/tex]
