Question

five workers take 12 days to weed a field . how many days would 6 workers take? how many days 15 workers take?​

Answer 1

Step-by-step explanation:

In one day, one worker weeds $\huge\bold{1/5 x 1/12 = 1/60}$1/5 x 1/12 = 1/60 of the field.

In one day, six workers could weed 6/60 or 1/10 of the field, so it would take them 10 days to weed the whole field.

In one day, 15 workers could weed 15/60 or 1/4 of the field, so the whole field would take 4 days.

Answer 2

If 5 workers take 12 days

Then , 1 worker will take = 5 × 12 = 60 days

So, 15 workers will take = 60 ÷ 15 = 4 days
