Answer 2

Calculation of the Total Area Plowed by the Tractorist

To calculate the total area plowed by the tractorist over three days, we need to add up the areas plowed on each day.

On the first day, the tractorist plowed 4/15 of the field. On the second day, the tractorist plowed 2/5 of the field. On the third day, the tractorist plowed the remaining 4.5 hectares of the field.

To find the total area plowed, we can add these three values together.

4/15 + 2/5 + 4.5 hectares

To simplify the calculation, we can convert the fractions to a common denominator.

4/15 + 6/15 + 4.5 hectares

Now, we can add the fractions together.

10/15 + 4.5 hectares

To add the fraction and the decimal, we need to convert the fraction to a decimal.

10/15 = 0.6667

Now, we can add the decimal and the decimal.

0.6667 + 4.5 hectares

Calculating the sum:

0.6667 + 4.5 = 5.1667 hectares

Therefore, the tractorist plowed a total of 5.1667 hectares of the field over three days.
