Question

An alloy is composed of nickel, zinc, and copper in a ratio of 7:2:9. How many kilograms of each metal are needed to make 3.6 kg of this alloy?

Answer 1

Answer:

Nickel= 1.8 kg

Zinc= 0.4 kg

Copper= 1.8 kg

Step-by-step explanation:

7:2:9

7=nickel

2=zinc

9=copper

7+2+9=18

18×2=36

7×2=14 2×2=4 9×2=18

Divide by 10

14÷10=1.4 4÷10=0.4 18÷10=1.8

1.8+1.4+0.4= 3.6

1.8=nickel

0.4=zinc

1.8=copper

Answer 2

Answer:

Nickel = 1.4 kg, Zinc = 0.4 kg, Copper = 1.8 kg

Step-by-step explanation:

Just wanted to fix the other answer. Use the work they did (they explain the problem pretty well) but change out the Nickel for 1.4 instead of 1.8 (The work they did was correct though. Just the final answer was wrong)
