If a bag contains 400 coins, and 33 1 over 2 are nickels, how many nickels are there what percent of the coins are not nickels

Assuming the number is 331/2, or 331 over 2:

331/2 = 165.5 : 400 =.4138 x 100% = 41.38%

100% - 41.38% = 58.62% not nickels

If the number is 33 1/2, or 33 and one half

33 1/2 = 67.5 : 400 = 0.0838 x 100% = 8.38%

100% - 8.38% = 91.62% not nickels

215% percent

i hope thats right

if not im sorry
