One week before an examination day, a librarian monitored the number of students who visited the library. Then they compared it with the number of visits made in an average week. Approximately 2×103

visits were reflected in their logbook during this one-week period, while only about 5×102
were reflected on an average week. How many times higher is the number of library visits before examination day compared to the library visits in an average week? Your answer should be a whole number.(1 point)

To find how many times higher the number of library visits before examination day is compared to the average week, we can use the following formula:

\[ \text{Ratio} = \frac{\text{Number of visits before examination}}{\text{Number of average visits}} \]

Given:

  • Number of visits before examination day: \( 2 \times 10^3 = 2000 \)
  • Number of average visits: \( 5 \times 10^2 = 500 \)

Now we can calculate the ratio:

\[ \text{Ratio} = \frac{2000}{500} = 4 \]

Thus, the number of library visits before examination day is approximately 4 times higher than the number of visits in an average week.
