Answer: If the number of builders increases, the time taken to complete the task should decrease.We can set up a proportion:6 days / 1 builder = x days / 5 buildersWhere x is the number of days it would take 5 builders to complete the wall.To solve for x, we can cross-multiply:6 days * 5 builders = 1 builder * x daysSimplifying:30 days = x daysTherefore, it would take 5 builders 30 days to build a similar wall.6×5 = 30
