Respuesta :

390 fans cheered because 780 divided by 2 is 390

the percent is 50% because one half is equal to 50%(take 100 for example)
   If it is asking for 1/2 (one half) that means we have to divide 780 by two, or split it into two equal parts and keep only one of them.

  780 divided by 2 = 390.

  1/2 also means the exact same thing as 50%.

  Your answer is 390 for both questions.

  Hope I helped :)
