ruby,if-statement , Refactoring if elsif else in Ruby

## Question:

Tag: ruby,if-statement

Is there a way to refactor this code and make it cleaner? Can you use fewer booleans to solve this problem?

def get_grade(grade_num)
return "Please enter a number between 0 and 100"
return 'A'
return 'B'
return 'C'
return 'D'
return 'F'
end
end


What about using Range and a case statement?

def get_grade(grade)
when 90..100 then 'A'
when 80...90 then 'B'
when 70...80 then 'C'
when 60...70 then 'D'
when  0...60 then 'F'
else
'Please enter a number between 0 and 100'
end
end
