Niether US nor Canadian quarters have ever been made of zinc. Please check your coin again and post a new, separate question with its date and country of origin.

US quarters were made of 905 silver and 10% copper until 1964. Since they they've been made of cupronickel outer layers bonded to a pure copper core.

Canadian quarters were made of 80% silver, then 50% silver, followed by pure nickel and finally plated steel

% rate = 500% = 25/5 * 100% = 5 * 100% = 500% quarter = 25 cents nickel = 5 ce nts

1 quarter is 1 quarter of a dollar so as a fraction it is 1/4 → it is 1/4 of 100% = 25 %.

percent increase = 50% % increase =|original value - new value|/original value * 100% = |20 - 30|/20 * 100% = 10/20 * 100% = 0.50* 100% = 50%

(value/total value)*100= (8.3/37.5)*100= 22.13%

2.02%% increase =|original value - new value|/original value * 100%= |94.1 - 96|/94.1 * 100%= 1.9/94.1 * 100%= 0.0202 * 100%= 2.02%

6/24ths is a quarter, so a quarter of 100 is 25, the answer is 25%

1 quarter:= 1/4:= 0.25 x 100%= 25%

10/25 times 100 .40 x 100 = 40%

25 per cent is a quarter and a quarter of 4 is 1. So a quarter of 400 is 100. Exact answer straight away! No estimation required.

Percent error = (actual value - theoretical value) / theoretical value * 100%

Since 100 percent represents the whole of a value, 100 percent of 7.5 is equal to 7.5.

100

Percent Error = {Absolute value (Experimental value - Theoretical Value) / Theoretical Value }*100

Yes.
