Question

60% of a museum fossils are from the Jurassic period. If the number of fossils from the Jurassic is 15,what’s the total number of fossils at the museum

Answer 1

The total number of fossils at the museum is 25. If you divide 15 by 60%, you get 25. To check to see if that makes sense, multiple 25 by 60% and you should get 15. By getting 15, you now have 60% of the total fossils at the museum, proving that the total amount of fossils is 25.
