In a recent year, 39% of all college students were enrolled part time. If 6.3 million college students were enrolled part-time that year, what was the total number of college students? Round your answer to the nearest million.
Let's denote the total number of college students as T. We know that 39% of all college students were enrolled part-time, or in other words, 39% of T is equal to 6.3 million. We can set up the equation:
0.39T = 6.3 million
To solve for T, we can divide both sides of the equation by 0.39:
T = 6.3 million / 0.39
T ≈ <<6300000/0.39=16153846.15>>16,153,846.15
Rounding to the nearest million, the total number of college students is approximately 16 million. Answer: \boxed{16}.
