化简 999.9999800000000…(6*10^{-3})

解答

化简

999.9999800000000 \dots (6 \cdot 1 0^{- 3})

\frac{149999997}{25000000}

十进制

5.99999988

求解步骤

999.99998 (6 \cdot 1 0^{- 3})

1 0^{- 3} = \frac{1}{1000}

= 999.99998 \cdot 6 \cdot \frac{1}{1000}

6 \cdot \frac{1}{1000} = \frac{3}{500}

= 999.99998 \cdot \frac{3}{500}

999.99998 = \frac{49999999}{50000}

= \frac{49999999}{50000} \cdot \frac{3}{500}

\frac{49999999}{50000} \cdot \frac{3}{500} = \frac{149999997}{25000000}

= \frac{149999997}{25000000}
