1. 26% liczby 55[tex]\frac{5}{13}[/tex] = [tex]\frac{26}{100}[/tex] × 55[tex]\frac{5}{13}[/tex] = [tex]\frac{26}{100}[/tex] × [tex]\frac{741}{13}[/tex] = 14,82
2. 44% liczby 4,(09) = 44% liczby [tex]\frac{405}{99}[/tex] = [tex]\frac{44}{100}[/tex] × [tex]\frac{405}{99}[/tex] = [tex]\frac{9}{5}[/tex] = 1[tex]\frac{4}{5}[/tex]
3. 5% liczby 5[tex]\frac{2}{5}[/tex] = [tex]\frac{5}{100}[/tex] × [tex]\frac{27}{5}[/tex] = [tex]\frac{27}{100}[/tex] = 0,27
4. 30% liczby 12[tex]\frac{2}{3}[/tex] = [tex]\frac{30}{100}[/tex] × [tex]\frac{38}{3}[/tex] = [tex]\frac{380}{100}[/tex] = 3,8
5. 75% liczby 101[tex]\frac{1}{5}[/tex] = [tex]\frac{75}{100}[/tex] × [tex]\frac{506}{5}[/tex] = [tex]\frac{3795}{50}[/tex] = 75,9
