tolong.........plissss pake cara

2.3/5=0.6
30%=0.3
1 3/8=1.375
1.35=1.35
Dari yg terkecil=30% ; 3/5 ; 1.35 ; 1 3/8(C)
3.3 1/8 - 1 5/12= 25/8 - 17/12= 75/24-34/24=41/24=1 17/24(C)
MAAF BGT YH KALAU SALAH

2. 30% = 30/100 = 3/10 = 240/800
    1 3/8 = 11/8 = 1100/800
    1,35 = 1 35/100 = 135/100 = 1080/800
    3/5 = 480/800
    Jadi urutannya adalah 30%, 3/5, 1,35 dan 1 3/8 (C)
3. 3 1/8 - 1 5/12 = 25/8 - 17/12 = 75/24 - 34/24 = 41/24 = 1 17/24 (C)
