Arrange the following marks obtained by students in ascending order and represent them on the number line 12, 4, 6, (-1), (-3 ). What is the difference between the student who scored the highest mark and the one who scored the lowest? [3 MARKS]

Answer:
:
Ascending order : 1 Mark
Number Line : 1 Mark

Marks obtained by the students = 12, 4, 6 , (-1), (-3 )
Marks arranged in ascending order = (-3) , (-1), 4, 6, 12
