a) zwykłych lub mieszanych
63% = [tex]\frac{63}{100}[/tex]
55% = [tex]\frac{55}{100} = \frac{11}{20}[/tex]
135% = [tex]1\frac{35}{100} = 1\frac{7}{20}[/tex]
60,75% = [tex]\frac{60,75}{100} = \frac{\frac{6075}{100} }{100} = \frac{\frac{234}{4} }{100} = \frac{243}{4} * \frac{1}{100} = \frac{243}{400}[/tex]
b) dziesiętnych
53% = 0,53
4% = 0,04
120% = 1,2
17,6% = 0,176
0,8% =0,008
