In 1990 a total of 100 earthquakes occurred worldwide, some but not all of which occurred in Asia.

Choose the correct choice from the following
A) 2/8
B) 1/3
C) 2/7
D) 1/4
E) 1/25
We're given a couple of facts to work with:   1) There were a total of 100 earthquakes   2) Of those earthquakes, 25 of them occurred in Asia   We're asked for the ratio of the number of earthquakes that occurred IN ASIA to the number of earthquakes that DID NOT occur in Asia.   Thus, there were 75 earthquakes that DID NOT occur in Asia....   The answer to the question is 25/75 ie. 1/3   Answer : 1/3
