Answer 2

Ответ:

1) 1/5+1/10=3/10(растений) — посадил садовник во второй день.

2) 1/5+3/10=5/10=1/2(растений) — посадил садовник за два дня.

3)1-1/2=2/2-1/2=1/2(растений) — осталось посадить.

Problem Analysis

The gardener planted 1/5 of all the plants on the first day and 1/10 more than that on the second day. We need to find the total fraction of plants planted by the gardener in two days and the fraction of plants that are still left to be planted.

Solution

Let's assume that the total number of plants is represented by the variable `x`.

On the first day, the gardener planted 1/5 of all the plants, which is equal to (1/5) * x = x/5.

On the second day, the gardener planted 1/10 more than what was planted on the first day. This means the gardener planted (x/5) + (1/10) * (x/5) = (x/5) + (x/50) = (11x/50).

To find the total fraction of plants planted by the gardener in two days, we add the fractions planted on each day: (x/5) + (11x/50) = (10x/50) + (11x/50) = (21x/50).

Therefore, the gardener planted 21x/50 of all the plants in two days.

To find the fraction of plants that are still left to be planted, we subtract the fraction planted from 1: 1 - (21x/50) = (50/50) - (21x/50) = (29x/50).

Therefore, 29x/50 of the plants are still left to be planted.

Answer

The gardener planted 21x/50 of all the plants in two days, and 29x/50 of the plants are still left to be planted.
