pakai cara...........

1/3=0,33
3/2=1,5
-------------  +
11/6=1,88
3X0,25=0,75=3/4

11/6-3/4=22/12-9/12=13/12=1[tex] \frac{1}{12}[/tex]
SEMOGA MENBANTU!!

jumlah tepung = 1/3 + 1 1/2 = 1/3 + 3/2 = 2/6+9/6 = 11/6 kg

diapakai utnk kue = 3 x 0,25 kg = 3 x 1/4 = 3/4 kg

sisa = 11/6 - 3/4 = 22/ 12 -9/12
                           = 13/12
                            = 1 1/12 kg
jawab.b. 1 1/12
