What is the product of −3 1/4 and −1 1/2 ? Enter your answer as a mixed number, in simplified form, in the box.

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 [tex]4\frac{7}{8}[/tex] and the simplified form of this mixed number is [tex]\frac{39}{8}[/tex].

Step-by-step explanation:

The two mixed numbers are

[tex]-3\frac{1}{4}=-\frac{13}{4}[/tex]

and [tex]-1\frac{1}{2}[/tex]

= [tex]-\frac{3}{2}[/tex]

Now we will multiply these negative fractions.

[tex](-\frac{13}{4})(-\frac{3}{2})[/tex]

When two negative signs get multiplied they become positive.

= [tex]\frac{13}{4}\times \frac{3}{2}[/tex]

= [tex]\frac{39}{8}[/tex]

= [tex]4\frac{7}{8}[/tex]

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