Calculation of the Number of Days Worked on Two Construction Sites

To calculate the number of days the builders worked on two construction sites, we need to use the information provided. According to the statement, the builders worked for 9 days on one construction site, which is 7 times less than the time they worked on the other construction site.

Let's denote the number of days worked on the first construction site as x. According to the given information, the number of days worked on the second construction site is 7 times greater than x.

To find the number of days worked on the second construction site, we can multiply x by 7.

Therefore, the number of days worked on the second construction site is 7x.

Now, let's substitute the value of x with 9 (the number of days worked on the first construction site) to find the number of days worked on the second construction site:

7x = 7 * 9 = 63

So, the builders worked for 63 days on the second construction site.

To summarize: - The builders worked for 9 days on one construction site. - The builders worked for 63 days on the other construction site.
