Answer:

 m + 180

 ———————

    4  

Step-by-step explanation:

  1

Simplify   —

           4

Equation at the end of step  1  :

        1

 45 +  (— • m)

        4

Step  2  :

Rewriting the whole as an Equivalent Fraction :

2.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  4  as the denominator :

          45     45 • 4

    45 =  ——  =  ——————

          1        4    

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:

45 • 4 + m     m + 180

——————————  =  ———————

    4             4    

Final result :

 m + 180

 ———————

    4
