Answer 1

Step-by-step explanation:

m, workers and d,days are inversely proportional

m1*d1 = m2*d2

5×9 = 3*d2

d2 = 15 days

takes 15 days for 3 workers

Answer 2

Answer: x = 15 days

Step-by-step explanation:

Given : 5 workers can paint a house in 9 days

To Find : In how many days 3 workers can complete the same task

Solution :

5 workers can paint a house in 9 days

3 workers can complete the same task in x days.

⇒ $5 * 9 = 3 * x$

⇒ $x = \frac{5 * 9}{3}$

∴ x = 15 days
