1/2*16(27+19)

解答

\frac{1}{2} \cdot 16 (27 + 19)

解答

368

求解步骤

\frac{1}{2} \cdot 16 (27 + 19)

遵循 PEMDAS 运算顺序

计算括号内的值

(27 + 19) : 46

27 + 19

27 + 19 = 46

= 46

= \frac{1}{2} \cdot 16 \cdot 46

乘除（左右）

\frac{1}{2} \cdot 16 \cdot 46 : 368

\frac{1}{2} \cdot 16 \cdot 46

\frac{1}{2} \cdot 16 = 8

\frac{1}{2} \cdot 16

将项转换为分式:

16 = \frac{16}{1}

= \frac{1}{2} \cdot \frac{16}{1}

使用分式法则:

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

= \frac{1 \cdot 16}{2 \cdot 1}

\frac{1 \cdot 16}{2 \cdot 1} = 8

\frac{1 \cdot 16}{2 \cdot 1}

\frac{1 \cdot 16}{2 \cdot 1} = \frac{16}{2}

\frac{1 \cdot 16}{2 \cdot 1}

数字相乘:

1 \cdot 16 = 16

= \frac{16}{2 \cdot 1}

数字相乘:

2 \cdot 1 = 2

= \frac{16}{2}

= \frac{16}{2}

数字相除:

\frac{16}{2} = 8

= 8

= 8

= 8 \cdot 46

8 \cdot 46 = 368

= 368

= 368

1 8^{2} - 8^{2}

(-6+16-24)/(-6-16+24)

\frac{- 6 + 16 - 24}{- 6 - 16 + 24}

3\div 3/5+1 7/24

3 \div \frac{3}{5} + 1 \frac{7}{24}

- 8 + 5 - 3 + 4
