It wants you to make it an in improper fraction

Answer 2

The expression
`-12 (1)/(2)+5 (3)/(4)` is equal to
`-(50)/(4)+(23)/(4)`.

To simplify the expression
`-12 (1)/(2)+5 (3)/(4)` , you can first convert the mixed numbers to improper fractions and then combine them:

`\begin{aligned}& -12 (1)/(2)=-(25)/(2) \\& 5 (3)/(4)=(23)/(4)\end{aligned}`

Now, the expression becomes
`-(25)/(2)+(23)/(4)`.

To add these fractions, we need a common denominator, which is 4 in this case.

`-(25)/(2)` is equivalent to
`-(25)/(2) * (2)/(2)=-(50)/(4)`

Now the expression becomes
`-(50)/(4)+(23)/(4)`

So, the correct option is B.
