Answer 1

Answer:    $\frac{1}{30\\}$

Step-by-step explanation:

No. of workers ------- No. days --------------No. of house

30                                20                                 1

1                                   20                                  ?

the no of days is same so we can simplify the equation that

30 worker built 1 house in 20 days

1 worker can built in 20 days will be

1/30 as the No of worker is ∝ $\frac{1}{amount of work done\\}$

A worker can built  $(1/30)^{th}$ part of the house.

Hope that it will help  you.
