Perform the indicated operations and simplify: ( − 5 − 8 ) ( − 5 1 3 )

To determine

To calculate: The simplified form of the expression (58)(513) by performing the indicated operation.

Explanation

Given Information:

The provided expression is (58)(513).

Formula used:

1. 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.

In case of ab=ab, use dividing signed numbers rules.

2. Multiplying two signed numbers includes:

1. In order to multiply two numbers having same sign, their absolute values must be multiplied. With this a positive result will be obtained.

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

3. Dividing two signed numbers includes:

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

(ii) 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:

(58)(513)

First, change the mixed number to fraction
