解答

化简

- 2 (11 - 105) + \frac{900 - 76 105}{45}

\frac{- 90 + 14 105}{45}

十进制

1.18794 \dots

求解步骤

- 2 (11 - 105) + \frac{900 - 76 105}{45}

将

- 2 (11 - 105)

转换为分数

: \frac{- 90 ( 11 - 105 )}{45}

= \frac{- 90 ( 11 - 105 )}{45} + \frac{900 - 76 105}{45}

\frac{- 90 ( 11 - 105 )}{45} + \frac{900 - 76 105}{45} = \frac{- 90 ( 11 - 105 ) + 900 - 76 105}{45}

= \frac{- 90 ( 11 - 105 ) + 900 - 76 105}{45}

化简

- 90 (11 - 105) + 900 - 76105 : - 90 + 14105

= \frac{- 90 + 14 105}{45}
