110+(70%× 110)

解答

110 + (70% \cdot 110)

解答

187

求解步骤

110 + (70% \cdot 110)

遵循 PEMDAS 运算顺序

计算括号内的值

(70% \cdot 110) : 77

70% \cdot 110

乘除（左右）

Convert

70%

into a fraction:

\frac{70}{100}

70%

Rewrite

70%

as

\frac{70}{100}

= \frac{70}{100}

= \frac{70}{100} \cdot 110

消掉

\frac{70}{100} : \frac{7}{10}

\frac{70}{100}

因式分解数字:

70 = 10 \cdot 7

= \frac{10 \cdot 7}{100}

因式分解数字:

100 = 10 \cdot 10

= \frac{10 \cdot 7}{10 \cdot 10}

约分:

10

= \frac{7}{10}

= \frac{7}{10} \cdot 110

\frac{7}{10} \cdot 110 = 77

\frac{7}{10} \cdot 110

将项转换为分式:

110 = \frac{110}{1}

= \frac{7}{10} \cdot \frac{110}{1}

使用分式法则:

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

= \frac{7 \cdot 110}{10 \cdot 1}

消掉

\frac{7 \cdot 110}{10 \cdot 1} : 77

\frac{7 \cdot 110}{10 \cdot 1}

数字相乘:

10 \cdot 1 = 10

= \frac{7 \cdot 110}{10}

数字相除:

\frac{110}{10} = 11

= 7 \cdot 11

数字相乘:

7 \cdot 11 = 77

= 77

= 77

= 77

= 110 + 77

加减（左右）

110 + 77 : 187

110 + 77

110 + 77 = 187

= 187

= 187
