There is a certain type of question I am having trouble with it has to do with percentages. Here is an example:
In 2006, a total of 2748 earthquakes occurred in the United States. Of these, 85.3% were minor tremors with magnitudes of 3.9 or less on the Richter scale. How many minor earthquakes occurred in the United States in 2006? Round to the nearest whole number.
The answer is 2344 earthquakes.
I can't for the life of me figure out how to get this number. I figure it has to do with dividing but I not sure dividing what. Please if you could show work I would greatly appreciate it! So I can apply the same principles to other like questions.
