Positive and a positive, will always be a positive because theyre both the same. If two things are the same, theyre equal. ( this is from what ik,I read it as a common sense question)
It's a proportion. 2 is to x as 15 is to 9, or 2/x = 15/9. Multiply the means and extremes 15x = 18 divide both sides by 15 to get x by itself. x = 1.2
