解答

化简

4.62 + \frac{31}{244} \cdot 1 \cdot 4.06 \cdot (1 - 0.4883)

\frac{231}{50} + \frac{32201281}{122000000}

十进制

4.88394 \dots

求解步骤

4.62 + \frac{31}{244} \cdot 1 \cdot 4.06 (1 - 0.4883)

4.62 = \frac{231}{50}

= \frac{231}{50} + \frac{31}{244} \cdot 1 \cdot 4.06 (1 - 0.4883)

4.06 = \frac{203}{50}

= \frac{231}{50} + \frac{31}{244} \cdot 1 \cdot \frac{203}{50} (1 - 0.4883)

\frac{31}{244} \cdot 1 \cdot \frac{203}{50} (1 - 0.4883) = \frac{32201281}{122000000}

= \frac{231}{50} + \frac{32201281}{122000000}
