If I understand your question correctly:

b = B.new  
b.toto

or:

B.new.toto

Well, I probably misunderstood your it the first time around 😉

Here’s probably what you were looking for:

class B \< A  
def tata  
toto  
end  
end

and then:

b = B.new  
b.tata

or:

B.new.tata

end

Sorry, but I make a mistake my class are :

class A  
def toto  
puts “tttt”  
end  
end

class B \< A  
def toto  
puts “mmmmm”  
end

def tata

end  
end

And I would like in B.tata to call the method toto of A.
