Question

If an alloy requires copper, nickel, and zinc in a ratio of 12:5:3, how many kilograms of each metal are needed to make 5 kg of the alloy?

Answer 1

Answer:   3 : 5/4 : 3/4

Step-by-step explanation:

12+5+3 = 20

5/20 = 1/4

12:5:3 * 1/4 = 3 : 5/4 : 3/4

Answer 2

Answer:

copper=3kg

nikhil=5/4 kg

zinc=3/4 kg

Step-by-step explanation:

copper:nikhil:zinc

12:5:3

let x be one value

12x+5x+3x=5

20x=5

x=5/20=1/4

12*1/4=12/4=3

5*1/4=5/4=1 1/4

3*1/4=3/4
