Question

Answer 1

Para resolver essa expressão, vamos seguir a ordem das operações matemáticas.Vamos calcular a expressão a)

2\frac {1}{3}

\frac{7}{3}

1\frac {2}{3}

\frac{5}{3}

3\frac {1}{2}

\frac{7}{2}

1\frac {3}{4}

\frac{7}{4}

1+(\frac{7}{3}-\frac{5}{3}):\frac{5}{6}+\frac{1}{2}(\frac{7}{2}+\frac{7}{4})

1+(\frac{2}{3}):\frac{5}{6}+\frac{1}{2}(\frac{14}{4}+\frac{7}{4})

1+(\frac{2}{3}):\frac{5}{6}+\frac{1}{2}(\frac{21}{4})

1+(\frac{2}{3} \times \frac{6}{5})+\frac{1}{2}(\frac{21}{4})

1+(\frac{4}{5})+\frac{1}{2}(\frac{21}{4})

1+\frac{4}{5}+\frac{21}{8}

1+\frac{32}{40}+\frac{105}{40}

1+\frac{137}{40}

1+3\frac{17}{40}

4\frac{17}{40}

1+(3\frac {3}{4}-2\frac {1}{4}):\frac {5}{4}+\frac {5}{3}\cdot (2\frac {2}{5}+1)

3\frac {3}{4}

\frac{15}{4}

2\frac {1}{4}

\frac{9}{4}

2\frac {2}{5}

\frac{12}{5}

1+(\frac{15}{4}-\frac{9}{4}):\frac{5}{4}+\frac{5}{3}(\frac{12}{5}+1)

1+(\frac{6}{4}):\frac{5}{4}+\frac{5}{3}(\frac{12}{5}+1)

1+(\frac{3}{2}):\frac{5}{4}+\frac{5}{3}(\frac{12}{5}+1)

1+(\frac{3}{2} \times \frac{4}{5})+\frac{5}{3}(\frac{12}{5}+1)

1+(\frac{6}{5})+\frac{5}{3}(\frac{12}{5}+1)

1+\frac{6}{5}+\frac{5}{3}(\frac{12}{5}+1)

1+\frac{6}{5}+\frac{5}{3}(\frac{17}{
