Odpowiedź:
a + 2[tex]\frac{1}{2} = 5\frac{3}{5}[/tex]
[tex]a = 5\frac{3}{5} -2\frac{1}{2} \\a = 5 \frac{6}{10} - 2 \frac{5}{10} \\a=3 \frac{1}{10}\\[/tex]
[tex]b - 5\frac{3}{4} = 7\frac{2}{3}\\b=7\frac{2}{3} + 5 \frac{3}{4} \\b= 7 \frac{8}{12} + 5 \frac{9}{12} \\b=12 \frac{17}{12} = 13 \frac{5}{12} \\[/tex]
4*c = 3[tex]\frac{5}{8}[/tex]
[tex]4*c = \frac{29}{8}[/tex]
[tex]c=\frac{29}{8} : 4\\c= \frac{29}{8} * \frac{1}{4} \\c= \frac{29}{32}[/tex]
