Solve

5 + 4 \cdot \frac{1}{2} : 7

Follow the PEMDAS order of operations

Multiply and divide (left to right)

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

4 \cdot \frac{1}{2}

Convert element to fraction:

4 = \frac{4}{1}

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

Apply the fraction rule:

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

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

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

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

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

5 + 2

5 + 2 = 7

= 7

= 7

= \frac{7}{7}

Apply rule

\frac{a}{a} = 1

= 1
