Odpowiedź:
a)1[tex]\frac{2}{7}[/tex] : [tex]\frac{4}{5}[/tex]=[tex]\frac{9}{7} *\frac{5}{4} =\frac{45}{28} =1\frac{17}{28}[/tex]
b)[tex]2\frac{7}{10} : 1\frac{2}{7} =\frac{27}{10} :\frac{9}{7} =\frac{27}{10} *\frac{7}{9} =\frac{3}{10} *\frac{7}{1} =\frac{21}{10} = 2\frac{1}{10}[/tex]
c) [tex]3\frac{3}{4} : 1 \frac{7}{8} =\frac{15}{4} :\frac{15}{8} =\frac{15}{4} *\frac{8}{15} =2[/tex]
Szczegółowe wyjaśnienie:
7,25*100=725
7,25*10=72,5
7,25*1000=7250
7,25*0,1=0,725
7,25*0,01=0,0725
7,25*0,001=0,00725
7,25:100=0,0725
7,25:0,01=725
7,25:1000=0,00725
7,25:0,1=72,5
7,25:0,001=7250
7,25:10=0,725
