Tolong dijawab besok ada ulangan nih

Bab Bilangan Pecahan
Matematika SD Kelas IV

a] 5/2 =
pecahan campuran = 2 1/2
pecahan desimal = (5 x 5)/(2 x 5) = 25/10 = 2,5
persen = 2,5 x 100% = 250%

b] 2 1/2
pecahan biasa = (2 x 2 + 1)/2 = 5/2
pecahan desimal = (5 x 5)/(2 x 5) = 25/10 = 2,5
persen = 2,5 x 100% = 250%

c] 1,25
persen = 1,25 x 100% = 125%
pecahan biasa = 125% = 125/100 = 5/4
pecahan campuran = 1 1/4

d] 250%
pecahan biasa = 250/100 = 5/2
pecahan campuran = 2 1/2
pecahan desimal = 250/100 = 2,5
