2/5 = 0.40
75% = 0.75
6/10 = 0.60
1/2 = 0.50
Terkecil ke terbesar = 0.25 , 0.4 , 0.5 , 0.6 , 0.75
= 0.25 , 2/5 , 1/2 , 6/10 , 75%
2). Diameter = 14cm
Radius (jari2) = Diameter : 2
= 14 : 2
= 7cm
Luas lingkaran = x radius^2
= 22/7 x 7 x 7
= 22 x 7
= 154cm^2
3). Luas Permukaan Balok = (2 x panjang x lebar) + (2 x panjang x tinggi) + (2 x lebar x tinggi)
= (2 x 20 x 15) + (2 x 20 x 5) + (2 x 15 x 5)
= 600 + 200 + 150
= 950cm^2
4). 1 1/6 + 2/5 + 2 1/4
= 7/6 + 2/5 + 9/4
= 70/60 + 24/60 + 135/60
= 229/60
= 3 49/60
