解答ステップ

0.99 (2 \cdot 1 0^{- 6})

1 0^{- 6} = \frac{1}{1000000}

= 0.99 \cdot 2 \cdot \frac{1}{1000000}

2 \cdot \frac{1}{1000000} = \frac{1}{500000}

= 0.99 \cdot \frac{1}{500000}

0.99 = \frac{99}{100}

= \frac{99}{100} \cdot \frac{1}{500000}

\frac{99}{100} \cdot \frac{1}{500000} = \frac{99}{50000000}

= \frac{99}{50000000}
