-1/3 – 2 * 1/4 + (9/8 ÷ 3/4)³=

Answer 1

A resolução é dada como:

$-\frac{1}{3} - 2*\frac{1}{4}+(\frac{9}{8}/\frac{3}{4})^3=\\\\=-\frac{1}{3} -\frac{1}{2}+(\frac{9}{8}*\frac{4}{3})^3=\\ \\=-\frac{2}{6}-\frac{3}{6}+(\frac{36}{24} )^3=\\\\= -\frac{5}{6} + (\frac{3}{2}) ^3 = \\\\=-\frac{5}{6} + \frac{27}{8}=\\ \\=-\frac{20}{24} + \frac{81}{24} =\\\\=\frac{61}{24}$

Com resultado final de 61/24
