13

Total Parts of Alloy = 13+7+5 => 25

% of Copper = \sf{\dfrac{13}{25}\times 100 = 13\times4=52\%}\\

% of Zinc = \sf{\dfrac{7}{25}\times100=7\times4=28\%}\\

% of Nickel = \sf{\dfrac{5}{25}\times100=5\times4=20\%}\\

Therefore, the total percent adds up to 100%.

So,

% of Copper = 52%

% of Zinc = 28%

% of Nickel = 20%

Hope it helps u

Have a great day ahead

Step-by-step explanation:

Total Parts of Alloy = 13+7+5

=> 25

% of Copper 13 =

25 x 100 = 13 x 4 = 52%

% of Zinc =

7 25 x 100 = 7 x 4 = 28%

% of Nickel =

5 25 x 100 = 5 x 4 = 20%

Therefore, the total percent adds up to 100%.

So,

% of Copper = 52% =

% of Zinc = 28%

% of Nickel = 20% =
