urutkan bilangan dari yang terkecil a.2/7,45%,0,5,0,7 b4/5,55%,45%,0,5c

a. 2/7 = (2x100)/(7x100) = 200/700
45% = 45/100 = (45x7)/(100x7) = 315/700
0,5 = 5/10 = (5x70)/(10x70) = 350/700
0,7 = 7/10 = (7x70)/(10x70) = 490/700
jadi, urutannya adlh = 2/7 ; 45% ; 0,5 ; 0,7

b. 4/5 = (4x20)/(5X20) = 80/100
55% = 55/100
45% = 45/100
0,5 = 5/10 = (5x10)/(10x10) = 50/100
jadi urutannya adlah = 45% ; 0,5 ; 55% ; 4/5
