We must compute the percentage of visitors due to Website C.
1) First, we compute the total number of visitors, which is equal to the sum of all the visits, the result in millions is:
[tex]\begin{gathered} \text{Total}=\text{Visits A + Visits B + Visits C + Visits D + Visits E} \\ \text{Total}=1619+1396+1228+893+447 \\ \text{Total}=5583 \end{gathered}[/tex]
2) Now, the percentage of visits due to website C is equal to the ratio of visits of C to the total multiplicated by 100:
[tex]\text{Percentage due to Website C = }\frac{\text{Visits C}}{\text{Total}}\cdot100=\frac{1228}{5583}\cdot100\cong21.995\cong22[/tex]
Answer
22% of the visitors of these five websites was due to Website C
