According to the information given in the exercise: About 47 million people (of a total of 74 million people) in the age group 21-24, have some college experience but no college degree.
Let be "x" the percent of the people in the age group 21-24 that have some college experience but have not earned a college degree.
Analyzing the information provided, you can identify that 74 million people in the age group 21-24 is the 100%. Then, you can set up the following proportion:
![(100)/(74,000,000)=(x)/(47,000,000)](https://img.qammunity.org/2023/formulas/mathematics/college/hw50fw1j140gnyd9wqkzqzl2eeek6o4wdh.png)
Now you can solve for "x":
![\begin{gathered} (47,000,000)((100)/(74,000,000))=x \\ \\ x\approx63.5 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/l7grm3ozv8b2gax8ej8pd11bf6f3xfxovw.png)
Therefore, the answer is: 63.5%
