Cześć ;-)
a)
[tex]1\frac{7}{10}=1,7\\\\\frac{3}{100}=0,03\\\\\frac{10}{16}=\frac{10:2}{16:2}=\frac{5}{8}=\frac{5\cdot125}{8\cdot125}=\frac{625}{1000}=0,625[/tex]
b)
[tex]0,25=\frac{25}{100}=\frac{25:25}{100:25}=\frac{1}{4}\\\\3,4=3\frac{4}{10}=3\frac{4:2}{10:2}=4\frac{2}{5}\\\\7,8=7\frac{8}{10}=7\frac{8:2}{10:2}=7\frac{4}{5}[/tex]
Pozdrawiam!
