In a recent year,

31%

of all college students were enrolled part-time. If

7.2

million college students were enrolled part-time that year, what was the total number of college students?

Round your answer to the nearest million.

To find the total number of college students, let’s set up the problem with the given dataTo find the total number of college students, let’s set up the problem with the given 

- 31% of all college students were enrolled part-time.
- The number of part-time students was 7.2 million.

We need to find the total number of college students, which we can denote as \( x \).

### Step-by-step approach:
1. The equation we can use is:
   \[
   0.31 \times x = 7.2
   \]
2. To solve for \( x \), divide both sides of the equation by 0.31:
   \[
   x = \frac{7.2}{0.31}
   \]

Now, let me calculate this.

\[
x = 23.23 \, \text{million}
\]

### Rounding:
The total number of college students is approximately **23 million**.
