Obliczenie do a) :
[tex] \frac{2}{3} \div 3 = \frac{2}{3} \times \frac{1}{3} = \frac{2}{9} [/tex]
Obliczenie do b) :
[tex]2.4 \div 0.4 = 24 \div 4 = 6[/tex]
Obliczenie do c) :
[tex] \frac{8}{5} \div \frac{4}{7} = \frac{8}{5} \times \frac{7}{4} = \frac{56}{20} = \frac{14}{5} = 2 \frac{4}{5} [/tex]
Obliczenie do d) :
[tex]720 \div 0.8 = 7200 \div 8 = 900[/tex]
