Question

Решите задачу:В колхозе на поливных землях собирали с гектара 60,8 ц пшеницы. Замена старого сорта пшеницы новым даёт прибавку урожая на 25%. Сколько теперь пшеницы собирает колхоз с 23 га поливного поля?

Answer 1

60,8 *25/100=15,2(ц)-прибавка после посева нового сорта пщеницы с 1 г. 2)60,8+15,2=76(ц)-урожайность с 1 г.     3)23*76=1748(ц)

Answer 2

Problem Analysis

To solve this problem, we need to calculate the amount of wheat the collective farm (kolhoz) will harvest from 23 hectares of irrigated land after replacing the old variety of wheat with a new one that increases the yield by 25%.

Solution

1. Calculate the yield per hectare after the variety replacement: - The old variety of wheat yields 60.8 centners (1 centner = 100 kilograms) per hectare. - The new variety increases the yield by 25%. - To calculate the new yield per hectare, we can multiply the old yield by 1.25. - New yield per hectare = 60.8 centners * 1.25 = 76 centners.

2. Calculate the total yield from 23 hectares of land: - Multiply the new yield per hectare by the number of hectares. - Total yield = New yield per hectare * Number of hectares = 76 centners * 23 hectares = 1748 centners.

Answer

The collective farm will harvest 1748 centners of wheat from 23 hectares of irrigated land after replacing the old variety with a new one that increases the yield by 25%.
