German Silver is an alloy composed of nickel, zinc, and copper in a ratio of 3:4:13.

How many kilograms of each metal are needed to make 4 kg of this alloy?

and then you get:

0.6 nickel
0.8 zinc
2.6 copper

no. Then you need to go back and multiply that by 3 ,4 and 13

To determine the amounts of each metal needed to make 4 kg of German Silver, we need to use the given ratio of nickel, zinc, and copper (3:4:13).

Step 1: Calculate the total number of parts in the ratio.
In this case, the total number of parts is 3 + 4 + 13 = 20.

Step 2: Calculate the proportion of each metal in relation to the total number of parts.
To calculate the proportion of each metal, divide the ratio by the total number of parts and multiply it by the total amount of the alloy required (4 kg in this case).

For nickel:
Proportion of nickel = (3/20) * 4 kg = 0.6 kg

For zinc:
Proportion of zinc = (4/20) * 4 kg = 0.8 kg

For copper:
Proportion of copper = (13/20) * 4 kg = 2.6 kg

Therefore, to make 4 kg of German Silver, you would need 0.6 kg of nickel, 0.8 kg of zinc, and 2.6 kg of copper.

If the amounts are 3x,4x,13x, then

3x+4x+13x = 4
20x = 4
Just finish it off from here.
