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

Answer:

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

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

25

13

×100=13×4=52%

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

25

7

×100=7×4=28%

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

25

5

×100=5×4=20%

Therefore, the total percent adds up to 100%.

So,

% of Copper = 52%

% of Zinc = 28%

% of Nickel = 20%
