Question

calcular o valor da expressão: (27⅓+64½-8⅔+4½)½

Answer 1

$(27 * \frac{1}{3} + 64 * \frac{1}{2} + 8 * \frac{2}{3} + 4 * \frac{1}{2} ) * \frac{1}{2} \\\\ ( \frac{27}{3} + \frac{64}{2} + \frac{16}{3} + \frac{4}{2} ) * \frac{1}{2}\\\\ ( \frac{54+192+32+12}{6} ) * \frac{1}{2} \\\\ \frac{290}{6} * \frac{1}{2} \\\\ \frac{290^{:2} }{12^{:2} } \\\\ \frac{145}{6}$
