Solution steps

12 \frac{1}{2} - (- 4 \frac{1}{2})

Convert mixed numbers to improper fractions:

12 \frac{1}{2} = \frac{25}{2}

= \frac{25}{2} - (- 4 \frac{1}{2})

Convert mixed numbers to improper fractions:

4 \frac{1}{2} = \frac{9}{2}

= \frac{25}{2} - (- \frac{9}{2})

Apply rule:

a - (- b) = a + b

\frac{25}{2} - (- \frac{9}{2}) = \frac{25}{2} + \frac{9}{2}

= \frac{25}{2} + \frac{9}{2}

\frac{25}{2} + \frac{9}{2} = 17

= 17
