Explanation:

Step1: Find total number of youths

The number of youths who prefer print books is 35 and who prefer electronic books is 38. So the total number of youths surveyed is $35 + 38=73$.

Step2: Calculate the percentage

The percentage of youths who prefer printed books is $\frac{35}{73}\times100\%$.
$ \frac{35}{73}\times100=\frac{3500}{73}\approx47.9452$.
Rounding to the nearest tenth of a percent gives 47.9%.

Answer:

47.9%
