D)

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

[tex] \frac{27}{40} = \frac{27 \times 25}{40 \times 25} = \frac{675}{1000} = 0.675[/tex]

E)

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

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

Mengubah ke bentuk desimal dan persen

d] 27/40 

Bentuk persen = 27/40 x 100% = 2.700/40 % = 67,5%
Bentuk desimal = 27/40 x 25/25 = 675/1.000 = 0,675

e] 17/50

Bentuk persen = 17/50 x 100% = 1.700/50 % = 34%
Bentuk desimal = 17/50 x 2/2 = 34/100 = 0,34
