Answer 1

1-вся работа
2/5+1/5=3/5 работы выполнено
1-3/5=2/5 - осталось невыполненной

Answer 2

Calculation of Remaining Work

To determine the remaining work, we need to calculate the total work completed by the master and subtract it from the total planned work.

The master initially completed 2/5 of the planned work, and then an additional 1/5 of the planned work.

To find the remaining work, we can add these two fractions together:

2/5 + 1/5 = 3/5

Therefore, 3/5 of the planned work has been completed, leaving 2/5 of the work remaining.
