If it takes 5 builders hours to build a wall, it will take 2 builders hours to build an identical wall
The time taken for 5 builders to build the wall = hours
The time take for 5 builders to build the wall = 3.5 hours
Time taken for 1 builder to build an identical wall =
5 x (Time taken for 5 builders to build the wall)
Time taken for 1 builder to build the wall = 5 x 3.5
Time taken for 1 builder to build the wall = 17.5 hours
Time taken for 2 builders to build an identical wall = (Time taken for 1 builder)/2
Time taken for 2 builders to build an identical wall = 17.5/2
Time taken for 2 builders to build an identical wall = 8.75 hours
Time taken for 2 builders to build an identical wall = hours

-8 3/8 = -8 15/40
-12 4/5 = -12 32/40 ,because you had to get a common denominator.
