Odpowiedź:
a) 7/8 *2 i 2/3= 7/8 *8/3 ( skracamy 8 i 8 przez 8 )= 7*1/3= 7/3= 2 i 1/3
b) 1 i 3/5 : 4/9= 8/5 *9/4 ( skracamy 8 i 4 przez 4)= 2/5 *9= 18/5= 3 i 3/5
c) ( 2/3)³= 2/3 *2/3*2/3= 8/27
Szczegółowe wyjaśnienie:
a)
[tex]\frac{7}{8} \times 2\frac{2}{3} = \frac{7}{8} \times \frac{8}{3} = \frac{7}{3} = 2 \frac{1}{3}[/tex]
b)
[tex]1\frac{3}{5} \div \frac{4}{9} = \frac{8}{5} \times \frac{9}{4} = \frac{18}{5} = 3\frac{3}{5}[/tex]
c)
[tex](\frac{2}{3})^{3} = \frac{2}{3} \times \frac{2}{3} \times \frac{2}{3} = \frac{8}{27}[/tex]
