Pembahasan

a.  [tex]\displaystyle \frac{1}{4}[/tex] = [tex]\displaystyle \frac{1\times 25}{4 \times 25} = \frac{25}{100}[/tex] = 25%

b. [tex]\displaystyle \frac{2}{5}[/tex] = [tex]\displaystyle \frac{2\times 20}{5 \times 20} = \frac{40}{100}[/tex] = 40%

c. [tex]\displaystyle \frac{4}{5}[/tex] = [tex]\displaystyle \frac{4\times 20}{5 \times 20} = \frac{80}{100}[/tex] = 80%

d. [tex]\displaystyle \frac{8}{10}[/tex] = [tex]\displaystyle \frac{8\times 10}{10 \times 10} = \frac{80}{100}[/tex] = 80%

e. [tex]\displaystyle \frac{11}{20}[/tex] = [tex]\displaystyle \frac{11\times 5}{20 \times 5} = \frac{55}{100}[/tex] = 55%

f. [tex]\displaystyle \frac{19}{20}[/tex] = [tex]\displaystyle \frac{19\times 5}{20 \times 5} = \frac{95}{100}[/tex] = 95%

g. [tex]\displaystyle \frac{10}{25}[/tex] = [tex]\displaystyle \frac{10\times 4}{25 \times 4} = \frac{40}{100}[/tex] = 40%

h. [tex]\displaystyle \frac{35}{50}[/tex] = [tex]\displaystyle \frac{35\times 2}{50 \times 2} = \frac{70}{100}[/tex] = 70%

i. [tex]\displaystyle \frac{20}{100}[/tex] = 20%
