Perform the indicated operations and simplify: ( − 4 9 ) ÷ ( − 2 )

To determine

To calculate: The simplified form of the expression (49)÷(2) by performing the indicated operation.

Explanation

Given Information:

The provided expression is:

(49)÷(2).

Formula used:

Equivalent signed fractions:

ab=ab=ab

The equivalent signed fraction shows that a negative fraction can be written in three different but equivalent forms.

Where,

ab Is the customary form.

And,

Dividing two signed numbers includes:

1. In order to divide two numbers having same sign, their absolute values must be divided. With this a positive quotient will be obtained.

2. And in order to divide two numbers with different signs, their absolute values must be divided and before the quotient a negative sign must be placed.

Calculation:

Consider the expression:

(49)÷(2)

First, change the given expression to customary form. That is,

(49)÷(2)=(49)÷(2)

Rewrite (2) as (21) in the above expression
