Answer:
-48/4
Step-by-step explanation:
This is a case of basic division. Simply solve all mixed numbers by dividing their numerators by their denominators.
45 ÷ 4 = 11 1/4
-51 ÷ 4 = -12 3/4
-48 ÷ 4 = -12 (Correct!)
-45 ÷ 4 = 11 1/4
NOTE to increase efficiency:
Solving all of those one by one can be an annoying/tedious process (especially with larger denominators), so if you would like to solve the problem faster, first realize that in order to get -12, you need the solution to be an integer. Therefore, your eyes can scroll through the four mixed numbers and see if the numerator is a multiple of 4 and therefore understand if the outcome will be an integer or a fraction.
