解

簡約

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

\frac{467}{112}

十進法表記

4.16964 \dots

解答ステップ

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

(\frac{1}{4})^{2} = \frac{1}{16}

- (3 (\frac{1}{4} - \frac{2}{7}) + 1) = - \frac{25}{28}

= \frac{1}{16} + 5 - \frac{25}{28}

\frac{1}{16} + 5 - \frac{25}{28} = \frac{467}{112}

= \frac{467}{112}
