化简 9*(1+5%)

解答

化简

9 \cdot (1 + 5%)

解答

\frac{189}{20}

+1

十进制

9.45

求解步骤

9 (1 + 5%)

= 9 (1 + 5% \cdot 1)

5% \cdot 1 = \frac{1}{20}

5% \cdot 1

Convert

5%

into a fraction:

\frac{5}{100}

5%

Rewrite

5%

as

\frac{5}{100}

= \frac{5}{100}

= \frac{5}{100} \cdot 1

\frac{5}{100} \cdot 1 = \frac{1}{20}

\frac{5}{100} \cdot 1

数字相乘:

\frac{5}{100} \cdot 1 = \frac{5}{100}

= \frac{5}{100}

对数字约分

\frac{5}{100} = \frac{1}{20}

= \frac{1}{20}

= \frac{1}{20}

= 9 (1 + \frac{1}{20})

1 + \frac{1}{20} = \frac{21}{20}

1 + \frac{1}{20}

将

1

转换为分数

: \frac{20}{20}

使用分式法则:

a = \frac{ab}{b}

= \frac{1 \cdot 20}{20}

数字相乘:

1 \cdot 20 = 20

= \frac{20}{20}

= \frac{20}{20} + \frac{1}{20}

\frac{20}{20} + \frac{1}{20} = \frac{21}{20}

\frac{20}{20} + \frac{1}{20}

使用分式法则:

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

= \frac{20 + 1}{20}

数字相加:

20 + 1 = 21

= \frac{21}{20}

= \frac{21}{20}

= 9 \cdot \frac{21}{20}

9 \cdot \frac{21}{20} = \frac{189}{20}

9 \cdot \frac{21}{20}

将项转换为分式:

9 = \frac{9}{1}

= \frac{9}{1} \cdot \frac{21}{20}

使用分式法则:

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

= \frac{9 \cdot 21}{1 \cdot 20}

数字相乘:

9 \cdot 21 = 189

= \frac{189}{1 \cdot 20}

数字相乘:

1 \cdot 20 = 20

= \frac{189}{20}

= \frac{189}{20}

流行的例子

5 + 3 \cdot 5

5 + 3 \cdot 2

5+(2+(3+2+(5+1)-7)+4)

5 + (2 + (3 + 2 + (5 + 1) - 7) + 4)

4*(7-4)+5*(4-7)+8

4 \cdot (7 - 4) + 5 \cdot (4 - 7) + 8
