Answer:
5 workers paint 2.5 houses in 5 days.
Step-by-step explanation:
10 workers paint 10 houses in 10 days.
1 worker is 1/10 the workforce of 10 workers, so:
1 worker paints 1 house in 10 days.
1 worker paints 0.5 house in 5 days.
5 workers are 5 times the workforce as 1 worker.
5 workers paint 2.5 houses in 5 days.
