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:

Now, percentage of copper = 13 25 × 100 = 52 % \frac{13}{25}\times100=52\% 2513×100=52%

Percentage of zinc = 7 25 × 100 = 28 % \frac{7}{25}\times100=28\% 257×100=28%

And percentage of nickel = 5 25 × 100 = 20 % \frac{5}{25}\times100=20\% 255×100=20%
