Calculating the Portion of the Field that Can Be Weeded in 5 Days

To calculate the portion of the field that can be weeded in 5 days, we can use the information provided. According to the information, for a 2.7-hectare field, it takes 3 days to weed. We can calculate the portion of the field that can be weeded in 5 days using the following formula:

Portion of field weeded in 5 days = (Weeding rate per day) x (Number of days)

Given that it takes 3 days to weed a 2.7-hectare field, we can calculate the weeding rate per day and then use it to find the portion of the field that can be weeded in 5 days.

Calculation

The weeding rate per day can be calculated as follows: Weeding rate per day = Total field size / Number of days to weed

Weeding rate per day = 2.7 hectares / 3 days Weeding rate per day = 0.9 hectares per day

Now, we can calculate the portion of the field that can be weeded in 5 days: Portion of field weeded in 5 days = 0.9 hectares/day x 5 days Portion of field weeded in 5 days = 4.5 hectares

So, the portion of the 2.7-hectare field that can be weeded in 5 days is 4.5 hectares.
