Hi DerpyIntelligence!
The product is addition so we do -3 1/4+-1 1/2. We solve it like this. We separate each part like this (-3)+(-1/4)+(-1)+(-1/2) then we solve the whole parts (-3)+(-1)=(-4). Next we find out the LCD of (-1/4) and (-1/2) which is 4 so we change (-1/2) to (-2/4) than we add (-1/4) which is (-3/4). Finally we add the wholes to the fractions (-4)+(-3/4)=(-4 3/4)
Hope this helps!

Answer:

Mixed number is 4\frac{7}{8} and the simplified form of this mixed number is \frac{39}{8}.

Step-by-step explanation:

The two mixed numbers are

-3\frac{1}{4}=-\frac{13}{4}

and -1\frac{1}{2}

= -\frac{3}{2}

Now we will multiply these negative fractions.

(-\frac{13}{4})(-\frac{3}{2})

When two negative signs get multiplied they become positive.

= \frac{13}{4}\times \frac{3}{2}

= \frac{39}{8}

= 4\frac{7}{8}

Therefore, mixed number is 4\frac{7}{8} and the simplified form of this mixed number is \frac{39}{8}.
