wrong

OpenStudy (mathstudent55):

Then what is the right answer?

OpenStudy (anonymous):

1/5488

OpenStudy (mathstudent55):

Incorrect. That is the number of suns that fit in the moon. The question is how many moons fit in the sun. The answer is 56 * 98.

well thats not the answer so I'm gonna stick with 1/5488

The question here is how to interpret "how many moons can the sun fit." Does that question mean how many moons fit in the sun, or how many suns fit in the moon? I say it means how many moons fit in the sun. The reason I choose that interpretation is from the first sentence in the problem. The first sentence reads "the sun can fit 56 earths." This is the same as saying the sun fits 56 earths. Since we know the sun is much larger than the earth, that sentence has to mean that 56 earths fit in the sun. With that interpretation in mind, now read the question "how many moons can the sun fit?" The number of moons the sun fits is similar to the sun fits 56 earths. Just like the sun is larger than the earth, and the earth is larger than the moon, the sun is much larger than the moon.
