A gold ore produces about 5 g of gold for every 1,000 kg of ore that is mined. If one ounce = 28.3 g, how many kg of ore must be mined to produce an ounce of gold?

Answers

ANSWER:

5660kg of ore must be mined to produce an ounce of gold.

If we use long multiplication to do 200×28.3 and evaluate the answer, it is 5660.

first find how much one gram of gold needs (how much ore) which is 200 kg of ore. Multiply that number 28.3. Because we are finding how much kg, we don’t need to convert the answer to grams.
