Odpowiedź:
zad.1
a) [tex]\frac{9}{12}[/tex] × 100% = 75%
b) [tex]\frac{2}{8}[/tex] × 100% = 25%
c) [tex]\frac{16}{25}[/tex] × 100% = 64%
d) [tex]\frac{18}{30}[/tex] ×100% = 60%
e) [tex]\frac{7}{14}[/tex] × 100% = 50%
f) [tex]\frac{4}{20}[/tex]× 100% = 20%
zad.2
[tex]\frac{9}{50}[/tex]= [tex]\frac{18}{100}[/tex] = 18%
[tex]\frac{7}{25}[/tex] = [tex]\frac{28}{100}[/tex] = 28%
[tex]\frac{18}{15}[/tex]= 1 [tex]\frac{3}{15}[/tex] = 1 [tex]\frac{1}{5}[/tex] = 1 [tex]\frac{20}{100}[/tex] =120%
[tex]\frac{49}{700}[/tex]= [tex]\frac{7}{100}[/tex] = 7%
[tex]\frac{53}{20}[/tex] =2 [tex]\frac{13}{20}[/tex] = 2 [tex]\frac{65}{100}[/tex] = 265%
[tex]\frac{50}{25}[/tex]= 2 = 200%
