Question

За 3 дня шестиклассники пропололи участок огорода. В первый день они пропололи 25% участка, во второй день 11/16 (дробь) остатка, а за третий день последние 60 м2 (квадратных). Какова прополотая площадь??

Answer 1

25% = 1/4
1) 1-1/4=3/4
2) 1-11/16=5/16
3)  60:5*16=192
4) 192:3*4=256 м2 - прополотая площадь

Answer 2

Problem Analysis

The problem states that a group of sixth graders cleared a portion of a garden in three days. On the first day, they cleared 25% of the area, on the second day, they cleared 11/16 of the remaining area, and on the third day, they cleared the last 60 square meters. We need to calculate the total area cleared by the students.

Solution

To find the total area cleared, we need to add up the areas cleared on each day.

1. On the first day, they cleared 25% of the area. 2. On the second day, they cleared 11/16 of the remaining area. 3. On the third day, they cleared the last 60 square meters.

Let's calculate the area cleared on each day step by step.

1. First day: - They cleared 25% of the area. - Let's assume the total area of the garden is x square meters. - The area cleared on the first day is 25% of x, which is 0.25x square meters.

2. Second day: - They cleared 11/16 of the remaining area. - After the first day, there is x - 0.25x = 0.75x square meters of area remaining. - The area cleared on the second day is 11/16 of 0.75x, which is (11/16) * 0.75x square meters.

3. Third day: - They cleared the last 60 square meters. - After the second day, there is 0.75x - (11/16) * 0.75x = (5/16) * 0.75x square meters of area remaining. - The area cleared on the third day is 60 square meters.

To find the total area cleared, we need to add up the areas cleared on each day:

Total area cleared = Area cleared on the first day + Area cleared on the second day + Area cleared on the third day

Let's calculate the total area cleared.

1. Area cleared on the first day: 0.25x square meters. 2. Area cleared on the second day: (11/16) * 0.75x square meters. 3. Area cleared on the third day: 60 square meters.

Total area cleared = 0.25x + (11/16) * 0.75x + 60 square meters.

Now, we need to solve this equation to find the value of x.

Unfortunately, the search results provided do not contain the necessary information to solve the equation and find the value of x. However, the equation can be solved using basic algebraic techniques.
