Explanation

Total students in A and B in 2012: 370 + 250 = 620. Total students in D and E in 2013: 420 + 430 = 850. Ratio: 620/850 = 62:85.

AI explanation

In 2012, the total students enrolled in colleges A and B were 370 plus 250, which equals 620. In 2013, the total students enrolled in colleges D and E were 420 plus 430, which equals 850. The ratio of these totals is 620 to 850. Dividing both sides of the ratio by their greatest common divisor of 10 yields the simplified ratio of 62 to 85.
