Calculating the Total Number of Workers on Two Construction Sites

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

Number of Workers on the First Construction Site: - 30 workers were working on the first construction site.

Number of Workers on the Second Construction Site: - The second construction site had 15 workers less than the first site.

Calculation

To find the total number of workers on the two construction sites, we can add the number of workers on the first site to the number of workers on the second site.

Total Number of Workers: - 30 (first site) + (30 - 15) (second site) = 30 + 15 = 45 workers

Therefore, a total of 45 workers worked on the construction of the two houses.
