Step-by-step explanation:
1) 1.2 cm, 0.6 in, 0.031 m, 0.1 ft
The relationship between the units is given as;
m > ft > in > cm
Upon converting the rest units to the lowest;
0.6 in = 1.524 cm
0.031 m = 3.1 cm
0.1 ft = 3.048 cm
The order is given as;
0.031 m > 0.1 ft > 0.6 in > 1.2 cm
2) 2 lb, 891 g, 1 kg, 0.02 T
2 lb = 907.185 g
1 kg = 1000 g
0.02 T = 20000 g
The order is given as;
0.02 T > 1 kg > 2 lb > 891 g
3) 1 1/4 c, 0.4 L, 950 mL, 0.7 gal
0.4 L = 400 mL
0.7 gal = 2649.79 mL
11/4 c = 650.6177 mL
The order is given as;
0.7 gal > 11/4 c > 950ml > 0.4 L
4) 4.5 ft, 48 in., 1.3 m, 120 cm
The relationship between the units is given as;
m > ft > in > cm
Upon converting the rest units to the lowest;
4.5 ft = 137.16 cm
48 in = 121.92 cm
1.3 m = 130 cm
The order is given as;
4.5 ft > 1.3 m > 48 in > 120 cm
