化简 (0.00123)/(1-1/1000)

解答

化简

\frac{0.00123}{1 - \frac{1}{1000}}

解答

\frac{41}{33300}

+1

十进制

0.00123 \dots

求解步骤

\frac{0.00123}{1 - \frac{1}{1000}}

\frac{0.00123}{1 - \frac{1}{1000}} = \frac{123}{100000 ( 1 - \frac{1}{1000} )}

= \frac{123}{100000 ( 1 - \frac{1}{1000} )}

化简

100000 (1 - \frac{1}{1000}) : 99900

= \frac{123}{99900}

因式分解数字:

123 = 3 \cdot 41

= \frac{3 \cdot 41}{99900}

因式分解数字:

99900 = 3 \cdot 33300

= \frac{3 \cdot 41}{3 \cdot 33300}

约分:

3

= \frac{41}{33300}
