求解步骤

14.85% (1 - 4%)

Convert

14.85%

into a fraction:

\frac{14.85}{100}

14.85%

Rewrite

14.85%

as

\frac{14.85}{100}

= \frac{14.85}{100}

= \frac{14.85}{100} (1 - 4%)

数字相除:

\frac{14.85}{100} = 0.1485

= 0.1485 (1 - 4%)

= 0.1485 (1 - 4% \cdot 1)

4% \cdot 1 = \frac{1}{25}

4% \cdot 1

Convert

4%

into a fraction:

\frac{4}{100}

4%

Rewrite

4%

as

\frac{4}{100}

= \frac{4}{100}

= \frac{4}{100} \cdot 1

\frac{4}{100} \cdot 1 = \frac{1}{25}

\frac{4}{100} \cdot 1

数字相乘:

\frac{4}{100} \cdot 1 = \frac{4}{100}

= \frac{4}{100}

对数字约分

\frac{4}{100} = \frac{1}{25}

= \frac{1}{25}

= \frac{1}{25}

= 0.1485 (1 - \frac{1}{25})

1 - \frac{1}{25} = \frac{24}{25}

1 - \frac{1}{25}

将

1

转换为分数

: \frac{25}{25}

1

使用分式法则:

a = \frac{ab}{b}

= \frac{1 \cdot 25}{25}

数字相乘:

1 \cdot 25 = 25

= \frac{25}{25}

= \frac{25}{25} - \frac{1}{25}

\frac{25}{25} - \frac{1}{25} = \frac{24}{25}

\frac{25}{25} - \frac{1}{25}

使用分式法则:

\frac{a}{c} - \frac{b}{c} = \frac{a - b}{c}

= \frac{25 - 1}{25}

数字相减:

25 - 1 = 24

= \frac{24}{25}

= \frac{24}{25}

= 0.1485 \cdot \frac{24}{25}

0.1485 = \frac{297}{2000}

0.1485

小数点后有几位数字就乘以和除以几次 10。

小数点右侧有

4

位，因此乘以和除以

10000

= \frac{10000 \cdot 0.1485}{10000}

数字相乘:

10000 \cdot 0.1485 = 1485

= \frac{1485}{10000}

消掉

\frac{1485}{10000} : \frac{297}{2000}

\frac{1485}{10000}

因式分解数字:

1485 = 5 \cdot 297

= \frac{5 \cdot 297}{10000}

因式分解数字:

10000 = 5 \cdot 2000

= \frac{5 \cdot 297}{5 \cdot 2000}

约分:

5

= \frac{297}{2000}

= \frac{297}{2000}

= \frac{297}{2000} \cdot \frac{24}{25}

\frac{297}{2000} \cdot \frac{24}{25} = \frac{891}{6250}

\frac{297}{2000} \cdot \frac{24}{25}

使用分式法则:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{297 \cdot 24}{2000 \cdot 25}

消掉

\frac{297 \cdot 24}{2000 \cdot 25} : \frac{891}{6250}

\frac{297 \cdot 24}{2000 \cdot 25}

因式分解数字:

24 = 8 \cdot 3

= \frac{297 \cdot 8 \cdot 3}{2000 \cdot 25}

因式分解数字:

2000 = 8 \cdot 250

= \frac{297 \cdot 8 \cdot 3}{8 \cdot 250 \cdot 25}

约分:

8

= \frac{297 \cdot 3}{250 \cdot 25}

\frac{297 \cdot 3}{250 \cdot 25} = \frac{891}{6250}

\frac{297 \cdot 3}{250 \cdot 25}

数字相乘:

297 \cdot 3 = 891

= \frac{891}{250 \cdot 25}

数字相乘:

250 \cdot 25 = 6250

= \frac{891}{6250}

= \frac{891}{6250}

= \frac{891}{6250}

= \frac{891}{6250}
