1. A scholar completed the problem below. Check their work. Explain how you know if each solution is correct or incorrect.

Convert the following measurements:

a. 55 km = 55,000m

b. 27 L = 27,000mL

c. 97 kg = 9,700 g

• It is correct, because all the conversions are correct.

• It is incorrect, because 27 L converts into 2,700 mL.

• It is incorrect, because 55 km converts into 55,000 km.

• It is incorrect, because 97 kg converts into 97,000 g.

Find the sum or difference:

27 kg 22 g – 21 kg 85 g

• 6,000 grams

• 537 grams

• 5,937 grams

• 6,063 grams
