$$(x+y)_{max.} = 2+2 = 4$$

$$(s+t)_{min.} = 0.4+0.4 = 0.8$$

largest possible value of (x+y)/(s+t) = $$(x+y)_{max.} / (s+t)_{min.}$$

largest possible value of (x+y)/(s+t) = $$4/0.8 = 5$$

Just and advise: Don't refer to barrons as it's a pathetic source to refer to and has multiple mistakes in the questions.

I hope this helps!!!
