(1\div 4)\div 2

解答

(1 \div 4) \div 2

解答

\frac{1}{8}

+1

十进制

0.125

求解步骤

(1 \div 4) \div 2

遵循 PEMDAS 运算顺序

计算括号内的值

(1 \div 4) : \frac{1}{4}

1 \div 4

1 \div 4 = \frac{1}{4}

= \frac{1}{4}

= \frac{1}{4} \div 2

乘除（左右）

\frac{1}{4} \div 2 : \frac{1}{8}

\frac{1}{4} \div 2

将项转换为分式:

2 = \frac{2}{1}

= \frac{1}{4} \div \frac{2}{1}

使用分式法则:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{1}{4} \cdot \frac{1}{2}

分式相乘:

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

= \frac{1 \cdot 1}{4 \cdot 2}

数字相乘:

1 \cdot 1 = 1

= \frac{1}{4 \cdot 2}

数字相乘:

4 \cdot 2 = 8

= \frac{1}{8}

= \frac{1}{8}

流行的例子

\frac{1}{5} (\frac{1}{2} + \frac{1}{13})

1 4^{2} - 1 2^{2}

2(-1)^2-6(-1)+3

2 (- 1)^{2} - 6 (- 1) + 3

- \frac{2}{3} (3) + 1

(2+2/5)\div 3/5

(2 + \frac{2}{5}) \div \frac{3}{5}
