=-21/2

=-10 1/2

Answer 2

Concept:

To solve this question, we need to recall the following concepts:

• A fraction formed by the combination of a whole number and a fraction is called a mixed fraction. Example: $7\frac{4}{5}$ is a mixed fraction.

• Least common multiple (L.C.M.) of two numbers is the smallest positive number which is divisible by both the numbers.

Given:

The given expression is : -4 - $6\frac{1}{2}$

To Find:

The simplified form of the given expression.

Solution:

First we convert the given mixed fraction in the form of improper fraction.

     $6\frac{1}{2}=\frac{13}{2}$

Now the expression becomes :

-4 - $6\frac{1}{2}$   = - 4 - $\frac{13}{2}$

Taking L.C.M.

           =  $\frac{-8-13}{2}$

           =   $\frac{-21}{2}$

           =   $-10\frac{1}{2}$

Hence, the simplified form of expression is   $-10\frac{1}{2}$ .
