Given:

The expression is:


-6(1)/(4)-2(1)/(8)

To find:

The simplified form of the given expression.

Solution:

We have,


-6(1)/(4)-2(1)/(8)

Write the mixed fractions in the form of improper fractions.


=-(6(4)+1)/(4)-(2(8)+1)/(8)


=-(24+1)/(4)-(16+1)/(8)


=-(25)/(4)-(17)/(8)

Taking LCM, we get


=(2(-25)-17)/(8)


=(-50-17)/(8)


=(-67)/(8)

Now write this improper fraction in the form of mixed fraction.


=-(64+3)/(8)


=-\left((64)/(8)+(3)/(8)\right)


=-\left(8+(3)/(8)\right)


=-8(3)/(8)

Therefore, the correct option is B.
