According to the given data we have the following expression to solve:
- 1/2 + 3 1/2
To solve this expression we would have to make the following calculations:
First we would multiply 3 times 1/2
[tex]3\cdot\frac{1}{2}=\frac{3\cdot\:1}{1\cdot\:2}[/tex]So, we would get:
[tex]-\frac{1}{2}+\frac{3}{2}[/tex][tex]\text{Next, }\mathrm{Apply\: the\: fraction\: rule}\colon\quad \frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex][tex]So,\text{ }-\frac{1}{2}+\frac{3}{2}=\frac{-1+3}{2}[/tex][tex]\mathrm{Add\: the\: numbers\colon}\: -1+3=2[/tex]So, Finally we would get the fraction 2/2 that would be equal to 1.
Therefore, - 1/2 + 3 1/2=1
