Question

. В первый день картофель был убран с площади 17,8 га, что на 2,3 га меньше, чем во второй день, и на 3,2 га больше, чемв третий день. С какой площади был убран картофель вчетвертый день, если за все четыре дня он был убран с площади 70 га?

Answer 1

1 день 17.8 га
2 день 17,8+2.3=20,1 га
3 день 17,8-3,2=14,6 га
4 день 70-17,8-20,1-14,6=17,5 га

Answer 2

1)17.8+2.3=20.1га-во второй день.

2)17.8-3.2=14.6га-в третий день.

3)17.8+20.1+14.6=52.5га-за три дня.

4)70-52.5=17.5га-в четвёртый день.

Answer 3

Calculation of Potato Harvest Area

To calculate the area of potato harvest on the fourth day, we need to analyze the information provided.

According to the given information: - On the first day, the potato was harvested from an area of 17.8 hectares. - This is 2.3 hectares less than the area harvested on the second day. - It is also 3.2 hectares more than the area harvested on the third day. - The total area of potato harvest over the four days is 70 hectares.

Let's break down the information step by step:

1. On the first day, the potato was harvested from an area of 17.8 hectares. 2. This is 2.3 hectares less than the area harvested on the second day. 3. It is also 3.2 hectares more than the area harvested on the third day. 4. The total area of potato harvest over the four days is 70 hectares.

To find the area of potato harvest on the fourth day, we can set up the following equation:

Area on the first day + Area on the second day + Area on the third day + Area on the fourth day = Total area over four days

Let's solve the equation step by step:

1. Area on the first day = 17.8 hectares 2. Area on the second day = Area on the first day + 2.3 hectares - Area on the second day = 17.8 hectares + 2.3 hectares = 20.1 hectares 3. Area on the third day = Area on the first day - 3.2 hectares - Area on the third day = 17.8 hectares - 3.2 hectares = 14.6 hectares 4. Area on the fourth day = Total area over four days - (Area on the first day + Area on the second day + Area on the third day) - Area on the fourth day = 70 hectares - (17.8 hectares + 20.1 hectares + 14.6 hectares) - Area on the fourth day = 70 hectares - 52.5 hectares - Area on the fourth day = 17.5 hectares

Therefore, the area of potato harvest on the fourth day is 17.5 hectares.
