Question

4. When solving a subtraction problem, we apply the additive Inverse property. Change the following problem using the additive inverse property -8 1/ 2-9 3/4

Answer 1

$\begin{gathered} -8\frac{1}{2}-9\frac{3}{4} \\ \frac{-17}{2}\text{ - }\frac{39}{4} \\ =-18\frac{1}{4} \\ \text{The additive i}nverse\text{ of -18}\frac{1}{4\text{ }}is\text{ +18}\frac{1}{4} \\ -18\frac{1}{4}+18\frac{1}{4}=0 \end{gathered}$
