解答ステップ

4.88 + (9.76 - \frac{12.5}{103} (4.88)) \cdot 0.5

9.76 - \frac{12.5}{103} (4.88) = \frac{23607}{2575}

= 4.88 + \frac{23607}{2575} \cdot 0.5

4.88 = \frac{122}{25}

= \frac{122}{25} + \frac{23607}{2575} \cdot 0.5

0.5 = \frac{1}{2}

= \frac{122}{25} + \frac{23607}{2575} \cdot \frac{1}{2}

\frac{23607}{2575} \cdot \frac{1}{2} = \frac{23607}{5150}

= \frac{122}{25} + \frac{23607}{5150}

\frac{122}{25} + \frac{23607}{5150} = \frac{48739}{5150}

= \frac{48739}{5150}
