Use the ratio in a meaningful sentence

Question

Ratio under 15 years old equals 13,180 to the total population which equals 66,104 for the Midwest region.

Answer 1

In a regional population of 66,104, the number of children under the age of 15 is 13,180, or 19.94 percent of the total population. 

Answer 2

 I understand that there are 13,180 U15s and the TOTAL population in the stated region of interest is 66,104.  So the ratio of these two numbers is, when reduced, 3295 to 16526, or 0.1994 in decimal, rounded to 4 DP.
