Answer 2

This is a math problem. To solve this we create a ratio of the radius of Pluto to the Moon.

$\frac{737}{1079}$ showing that Pluto is about 68% the size of the moon. You asked if Pluto was less than $\frac{2}{3}$ or 66%, or less the size of the moon.

68>66 so the answer is False if you are talking about the volume or size of the two.

If you are talking about density, the ratio would be:

$\frac{1.88}{3.34}$ which equals 56% so the answer would be True if you are inquiring about density.

Did that answer your question?
