Question

Трактарист вспахал земельный участок за три дня. В первый день он вспахал 4/15 части от учаска , во второй день 2/5 части ,а в третий день осташийся 4,5 .Сколькогектаров трокторист вспахал за три дня

Answer 1

4 / 15 * x + 2 /5 * x + 4,5 = x
4 / 15 * x + 6 /15 * x + 4,5 = x
10 / 15 * x + 4,5 = x
10 / 15 * x - x = 4,5
5/15 * x = 4,5
x = 4,5 / (1/3)
x = 4,5 * 3
x = 13,5

Answer 2

Calculation of the Area Plowed by the Tractorist

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

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

To find the total area plowed, we can add these portions together:

4/15 + 2/5 + 4.5

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

4/15 + 6/15 + 4.5

Now, we can add the fractions:

10/15 + 4.5

To add the fractions 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 = 5.1667

Therefore, the tractorist plowed approximately 5.1667 hectares over the course of three days.

Please note that the exact area plowed may vary depending on the specific measurements and calculations used.
