di uhah dlm bntuk persen dan desimal.a.13/20= b.27/40= c.17/50= tlng di bntu ya

a.13/20=13/20×100=65%
65%= 65/100=0,65
b.27/40=27/40×100=2700/40=67,5%
67,5%=675/1000=0,675

13/20 :

Desimal

[tex] \frac{13}{20} = \frac{13 \times 5}{20 \times 5} = \frac{65}{100} = 0.65[/tex]

Persen :

[tex] \frac{13}{20} = \frac{13 \times 5}{20 \times 5} = \frac{65}{100} = 65\%[/tex]

___________________________

27/40

Desimal :

[tex] \frac{27}{40} = \frac{27 \times 25}{40 \times 25} = \frac{675}{1000} =0 .675[/tex]

Persen :

[tex] \frac{27}{40} \times 100 = 2.5 \times 27 = 67.5\%[/tex]

___________________________

17/50

Desimal :

[tex] \frac{17}{50} = \frac{17 \times 2}{50 \times 2} = \frac{34}{100} = 0.34[/tex]

Persen :

[tex] \frac{17}{50} = \frac{17 \times 2}{50 \times 2} = \frac{34}{100} = 34\%[/tex]
