seperating key and multiple values for print with .each

Question

I'm probably trying to be hard headed about this. I'm trying to format hash key and and array of values for output to user. Ruby-doc give me the code for it for one value. http://www.ruby-doc.org/core/classes/Hash.html#M002861

h = { "a" => 100, "b" => 200 }
h.each {|key, value| puts "#{key} is #{value}" }

I'm trying to get

h = { "a" => [100,'green'], "b" => [200,'red'] }
h.each {|key, m,n| puts "#{key} is #{m} and #{n}"}  

produces: 

a is 100 and green
b is 200 and red

I've had some luck with h.each{|key,m,n| puts "#{key} is #{[m,'n']} "}

it produces:

a is 100green
b is 200red

I need some space between my array of elements, how do I go about doing that?

Answer 1

h.each {|k,v| puts "#{k} is #{v[0]} and #{v[1]}"}

Answer 2

h.each {|key, (m, n)| puts "#{key} is #{m} and #{n}"}

Answer 3

h.each { |key, value| puts "#{key} is #{value.first} and #{value.last}" }

Answer 4

I'm a fan of each_pair for hashes:

h.each_pair {|key, val| puts "#{key} is #{val[0]} and #{val[1]}" }

Or

h.each_pair {|key, val| puts "#{key} is #{val.join(' and ')}"}
