Question

ПОМОГИТЕ! Решите задачу : За три дня собрано 532 кг семян деревьев. В 1 день собрали 1/2 этого количества, во второй день - 5/14 этого количества. Сколько килограммов семян было собрано в третий день? Ps: 1/2 это дробь и 5/14 тоже ! ! !

Answer 1

3 дня = 532кг

первый день 1/2, т.е. половина = 266

2 день = 532:14*5=190

за 2 дня=266+190=456

3 день=532-456=76

Answer 2

Problem Analysis

We are given that 532 kg of seeds were collected over three days. On the first day, half of this amount was collected, and on the second day, 5/14 of the total amount was collected. We need to find out how many kilograms of seeds were collected on the third day.

Solution

Let's break down the problem step by step.

1. On the first day, half of the total amount was collected. Therefore, the amount collected on the first day is: - 1/2 * 532 kg = 266 kg.

2. On the second day, 5/14 of the total amount was collected. Therefore, the amount collected on the second day is: - (5/14) * 532 kg = 190 kg.

3. To find the amount collected on the third day, we need to subtract the amounts collected on the first and second days from the total amount: - Total amount - Amount collected on the first day - Amount collected on the second day = Amount collected on the third day. - 532 kg - 266 kg - 190 kg = 76 kg.

Therefore, 76 kg of seeds were collected on the third day.

Answer

The amount of seeds collected on the third day is 76 kg.
