### Complexity=1, Mode=metric

Do the following conversions. Round to nearest tenth where necessary.

11000 mg = g
Solution
1000 mg × (1 g/1,000 mg) = 1 g
21000 mg = g
Solution
1000 mg × (1 g/1,000 mg) = 1 g

### Complexity=4, Mode=metric

Do the following conversions. Round to nearest tenth where necessary.

14000 mg = g
Solution
4000 mg × (1 g/1,000 mg) = 4 g
21000 g = kg
Solution
1000 g × (1 kg/1,000 g) = 1 kg

### Complexity=6, Mode=metric

Do the following conversions. Round to nearest tenth where necessary.

16 g = mg
Solution
6 g × (1,000 mg/1 g) = 6000 mg
21 kg = g
Solution
1 kg × (1,000 g/1 kg) = 1000 g

### Complexity=2, Mode=english

Do the following conversions. Round to nearest tenth where necessary.

11 lb = oz
Solution
1 lb × (16 oz/1 lb) = 16 oz
216 oz = lb
Solution
16 oz × (1 lb/16 oz) = 1 lb

### Complexity=4, Mode=english

13 lb = oz
Solution
3 lb × (16 oz/1 lb) = 48 oz
24000 lb = ton
Solution
4000 lb × (1 ton/2,000 lb) = 2 ton

### Complexity=4, Mode=mixed

Do the following conversions. Round to nearest tenth where necessary.

116 oz = lb
Solution
16 oz × (1 lb/16 oz) = 1 lb
23 kg = g
Solution
3 kg × (1,000 g/1 kg) = 3000 g

### Complexity=6, Mode=mixed

Do the following conversions. Round to nearest tenth where necessary.

164 oz = lb
Solution
64 oz × (1 lb/16 oz) = 4 lb
210000 lb = ton
Solution
10000 lb × (1 ton/2,000 lb) = 5 ton

### Complexity=2, Mode=complex

Do the following conversions. Round to nearest tenth where necessary.

11 oz = mg
Solution
1 oz × (1 lb/16 oz) × (1 kg/2.2046 lb) × (1,000,000 mg/1 kg) = 28349.8 mg
22 kg = oz
Solution
2 kg × (2.2046 lb/1 kg) × (16 oz/1 lb) = 70.5 oz
