Part 1

my_name = 'John Smith'
		
height_inches = 60
		
puts my_name + " is " + 
height_inches.to_s + " inches tall."

weight_pounds = 160

Part 2

puts "Hi! what's your name?"
my_name = gets.chomp
		
puts "How tall are you (in inches)?
height_inches = gets.chomp
		
puts "If you don't mind me asking,
how much do you weight?
weight_pounds = gets.chomp
			
puts "#{my_name} is #{height_inches} 
inches tall and weighs #{weight_pounds}"

Part 3

height_centimeters = height_inches * 2.54

puts "{my_name} is #{height_centimeters} cm 
and #{weight_kilograms} kg"

Completed Code

puts "Hi! what's your name?"
my_name = gets.chomp

puts "How tall are you (in inches)?"
height_inches = gets.chomp.to_f

puts "If you don't mind me asking,
how much do you weight?"
weight_pounds = gets.chomp.to_f

height_centimeters = height_inches * 2.54

weight_kilograms = weight_pounds * 0.453592

puts "#{my_name} is #{height_centimeters} cm and #{weight_kilograms} kg"
