Calculation of Builders' Work Days

To calculate the total number of days the builders worked on the two construction sites, we can use the information provided.

Let's denote: - The number of days the builders worked on the first construction site as x. - The number of days the builders worked on the second construction site as y.

Given: - The builders worked 9 days on one construction site, which is 7 times less than the time they worked on the other construction site.

We can express this information in the following equation: x = 9 and y = 7x.

Calculation

Using the given information, we can calculate the total number of days the builders worked on the two construction sites.

x = 9 (days on the first construction site)

y = 7x = 7*9 = 63 (days on the second construction site)

So, the builders worked for 9 days on one construction site and 63 days on the other construction site.

Therefore, the total number of days the builders worked on the two construction sites is 9 + 63 = 72 days.

This calculation is based on the given information and the relationship between the days worked on the two construction sites.
