Question

колхоз собрал 650 тонн зерна 80% всего зерна составляла пшеница а 5/26 остатка рожь сколько тонн ржи собрал колхоз?

Answer 1

Масса пшеницы m1=650*80/100=520 тонн.

Масса остатка: mо=650-520=130 тонн.

Масса ржи: m=5/26*130=25 тонн.

Ответ: 25 тонн ржи собрал колхоз.

Answer 2

650 : 100 = 6,5 сост.1%

6.5 х 80 =520  сост. пшеница

650-520=130  остаток

130 :26 х 5 =25 т сост рож

Answer 3

Calculation of Rye Harvested by the Collective Farm

To calculate the amount of rye harvested by the collective farm, we need to determine the percentage of rye in the total grain harvested and then calculate the quantity based on that percentage.

Given information: - The collective farm harvested a total of 650 tons of grain. - 80% of the total grain was wheat. - The remaining 5/26 of the total grain was rye.

Let's break down the calculation step by step:

1. Calculate the amount of wheat harvested: - 80% of 650 tons = 0.8 * 650 = 520 tons of wheat.

2. Calculate the remaining grain after wheat harvest: - Total grain - Wheat = 650 - 520 = 130 tons.

3. Calculate the percentage of rye in the remaining grain: - 5/26 of the remaining grain = (5/26) * 130 = 25 tons of rye.

Therefore, the collective farm harvested 25 tons of rye.

Please note that the calculation assumes that the given percentages are accurate and that there are no other types of grain harvested by the collective farm.
