化简 1 15/100+1/50+1.175

解答

化简

1 \frac{15}{100} + \frac{1}{50} + 1.175

2 \frac{69}{200}

十进制

2.345

求解步骤

1 \frac{15}{100} + \frac{1}{50} + 1.175

将带分数转换为假分式:

1 \frac{15}{100} = \frac{115}{100}

= \frac{115}{100} + \frac{1}{50} + 1.175

1.175 = \frac{47}{40}

= \frac{115}{100} + \frac{1}{50} + \frac{47}{40}

\frac{115}{100} + \frac{1}{50} + \frac{47}{40} = \frac{469}{200}

= \frac{469}{200}

将假分式转换为带分数:

\frac{469}{200} = 2 \frac{69}{200}

= 2 \frac{69}{200}
