Bab Bilangan Pecahan
Matematika SD Kelas IV

ubah ke pecahan desimal dan persen

1] 5/25 = (5 x 4)/(25 x 4) = 20/100
desimal = 0,20
persen = 20%

2] 4/50 = (4 x 2) / (50 x 2) = 8/100
desimal = 0,08
persen = 8%

3] 1/4 = (1 x 25) / (4 x 25) = 25/100
desimal = 0,25
persen = 25%

4] 13/20 = (13 x 5) / (20 x 5) = 65/100
desimal = 0,65
persen = 65%

5] 17/50 = (17 x 2) / (50 x 2) = 34/100
desimal = 0,34
persen = 34%
