A)

Persen :

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

Desimal :

2/5 = 2/5 x 2/2 = 4/10 = 0,4

B)

Persen :

4/25 = 4/25 x 4/4 = 16/100 = 16%

Desimal :

4/25 = 4/25 x 4/4 = 16/100 = 0,16

C)

Persen :

13/20 = 13/20 x 5/5 = 65/100 = 65%

Desimal :

13/20 x 5/5 = 65/100 = 0,65

Jawab 
a) 2/5 
    persen = 2/5 ×100%
                = 40%
    desimal = 40/100
                 = 0,4
b) 4/25
    persen = 4/25×100%
                = 16%
    desimal = 16/100
                 = 0,16
c) 13/20 
     persen = 13/20×100%
                 = 65%
     desimal = 65/100
                   =0,65

Semoga membantu :)
