Odpowiedź :
[tex]\frac{3}{7} = \frac{x}{56}[/tex]
7x = 3*56 = 168 | /7
x = 24
[tex]\frac{3}{7} = \frac{24}{56}[/tex]
[tex]\frac{3}{12} = \frac{27}{x}[/tex]
3x = 12*27 = 324 | /3
x = 108
[tex]\frac{3}{12} = \frac{27}{108}[/tex]
[tex]2\frac{3}{4}[/tex] = [tex]\frac{11}{4}[/tex]
[tex]7\frac{2}{7} = \frac{51}{7}[/tex]
[tex]\frac{25}{6} = 4\frac{1}{6}[/tex]
[tex]\frac{33}{7} =4 \frac{5}{7}[/tex]
6 = [tex]\frac{42}{7}[/tex]
4 = [tex]\frac{40}{10}[/tex]
