​

Answer 1

Resposta:

e=726 5/12

E na fôrma alternativa é

e=8717/12, e=726,416

$e = 36 \frac{1}{2} + 64 \frac{2}{3} + 625 \frac{1}{4} = \\ e = 36 \frac{1}{2} + 64 \frac{2}{3} + 625 \frac{1}{4} \\ e = (36 + 64 + 625) + ( \frac{1}{2} + \frac{2}{3} - \frac{1}{4}) \\ 36 + 64 + 625 \\ 100 + 625 \\ 725 \\ e = (36 + 64 + 625) + ( \frac{1}{2} + \frac{2}{3} + \frac{1}{4}) \\ e = 725 + ( \frac{1}{2} + \frac{2}{3} + \frac{1}{4}) \\ e = (36 + 64 + 625) + ( \frac{1}{2} + \frac{2}{3} + \frac{1}{4}) \\ \frac{1}{2} + \frac{2}{3} + \frac{1}{4} \\ \frac{6 + 8 + 3}{12} \\ \frac{17}{12} \\ e = (36 + 64 +625) + ( \frac{1}{2} + \frac{2}{3} + \frac{1}{4}) \\ e = 725 + \frac{17}{12} \\ e = 725 + 1 \frac{5}{12} \\ e = 725 + 1 + \frac{5}{12} \\ e = 726 + \frac{5}{12} \\ e = 726 \frac{5}{12} \\ resposta \\ e = 726 \frac{5}{12} \\ na \: forma \: alternativa \: e \: \\ e = \frac{8717}{12}. \: e =726.416$
