Solution

(10 \cdot 4) \frac{1}{2}

20

Solution steps

(10 \cdot 4) \frac{1}{2}

Follow the PEMDAS order of operations

Calculate within parentheses

(10 \cdot 4) : 40

10 \cdot 4

10 \cdot 4 = 40

= 40

= 40 \cdot \frac{1}{2}

Multiply and divide (left to right)

40 \cdot \frac{1}{2} : 20

40 \cdot \frac{1}{2}

Convert element to fraction:

40 = \frac{40}{1}

= \frac{40}{1} \cdot \frac{1}{2}

Apply the fraction rule:

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

= \frac{40 \cdot 1}{1 \cdot 2}

\frac{40 \cdot 1}{1 \cdot 2} = 20

\frac{40 \cdot 1}{1 \cdot 2}

\frac{40 \cdot 1}{1 \cdot 2} = \frac{40}{2}

\frac{40 \cdot 1}{1 \cdot 2}

Multiply the numbers:

40 \cdot 1 = 40

= \frac{40}{1 \cdot 2}

Multiply the numbers:

1 \cdot 2 = 2

= \frac{40}{2}

= \frac{40}{2}

Divide the numbers:

\frac{40}{2} = 20

= 20

= 20

= 20
