Question

try these conversions, using the ladder method. 1000 mg = g 1 l = ml 160 cm = mm 14 km = m 109 g = kg 250 m = km

Explanation:

Step1: Recall mass conversion

1 g = 1000 mg, so 1000 mg = 1 g.

Step2: Recall volume conversion

1 L = 1000 mL.

Step3: Recall length conversion

1 cm = 10 mm, so 160 cm = 160×10 = 1600 mm.

Step4: Recall length conversion

1 km = 1000 m, so 14 km = 14×1000 = 14000 m.

Step5: Recall mass conversion

1 kg = 1000 g, so 109 g = 109÷1000 = 0.109 kg.

Step6: Recall length conversion

1 km = 1000 m, so 250 m = 250÷1000 = 0.25 km.

Answer:

1000 mg = 1 g
1 L = 1000 mL
160 cm = 1600 mm
14 km = 14000 m
109 g = 0.109 kg
250 m = 0.25 km
