Question

Juli went mining and found a large metal bar that weighed 20 kilos. After doing some analysis of the
metal bar, she found out that 2/5 of the bar contains gold and the rest contains cooper. What’s the
amount of cooper in kilos in the metal bar that Juli found?

Answer 1

Answer:

8 kilos of it is gold, since 2/5 in decimal form is 0.40

12 kilos of it is copper.

Step-by-step explanation:

Multiply 20 times 0.40, you get 8, so 8 kilos of it is gold, while 12 kilos is copper.
