Question

answer of [56-{42+(19×7)43×(21+64)÷2}]​

Answer 1

Answer:

-243043.50000

Step-by-step explanation:

Step  1  :

           85

Simplify   ——

           2

Equation at the end of step  1  :

                      85

 56 -  (42 +  (5719 • ——))

                      2

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  2  as the denominator :

          42     42 • 2

    42 =  ——  =  ——————

          1        2  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

42 • 2 + 486115     486199

———————————————  =  ——————

       2              2  

Equation at the end of step  2  :

       486199

 56 -  ——————

         2  

Step  3  :

Rewriting the whole as an Equivalent Fraction :

3.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  2  as the denominator :

          56     56 • 2

    56 =  ——  =  ——————

          1        2  

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

56 • 2 - (486199)     -486087

—————————————————  =  ———————

        2                2  

Final result :

 -486087                

 ——————— = -243043.50000
