Question

A standard major league baseball has a mass of about 150 grams. An aspirin has a mass of about 300 milligrams. How many asprins would have about the same mass as one baseball?

Answer 1

There are 1,000 milligrams in 1 gram, so...
Let's divide

`300/1,000=0.3`
300 milligrams = 0.3 grams
Now...

`150/0.3=500`
500 aspirins would have about the same mass as one baseball
