Final answer:
To find the percentage of research and development sections that were audited, divide the number of audited sections by the total number of sections and multiply by 100. In this case, approximately 53.8% of the research and development sections were audited.
Step-by-step explanation:
To find the percentage of research and development sections that were audited, we need to divide the number of audited sections by the total number of sections and multiply by 100.
In this case, 7 sections were audited out of a total of 13 sections. So, the percentage of audited sections is:
% = (7/13) * 100 = 53.8%
Therefore, approximately 53.8% of the research and development sections were audited.
