Star Power and Temperature

Star A and Star B

Consider two stars that are the same size (they have the same diameter), but have different surface temperatures. Let’s say Star A’s temperature is 3000 K and Star B’s temperature is 4500 K.

Let’s look at the ratio of Star B’s temperature to Star A’s temperature. A “ratio” is simply a fraction. So in this case the numerator of this fraction is the temperature of Star B and the denominator is the temperature of Star A. What, then, is the ratio of Star B’s temperature to Star A’s temperature? Enter numbers and decimal point only.
