Hej!
[tex] \frac{7}{8} \times 2 \frac{2}{3} = \frac{7}{8} \times \frac{8}{3} = \frac{7}{3} = 2 \frac{1}{3} [/tex]
[tex]1 \frac{3}{5} \div \frac{4}{9} = \frac{8}{5} \times \frac{9}{4} = \frac{18}{5} = 3 \frac{3}{5} [/tex]
[tex] {( \frac{2}{3}) }^{2} = \frac{ {2}^{2} }{ {3}^{2} } = \frac{4}{9} [/tex]
Pozdrawiam! - Julka
