Question

Помогите пожалуйста решить задачу.При выпечке хлеба из 10 кг ржаной муки получается 14 кг хлеба. Сколько килограммов припёка получается? Сколько килограммов муки надо взять, чтобы получилось 28 кг припёка? Сколько килограммов хлеба получат из этой муки?

Answer 1

1) 14 - 10 = 4 (кг) - получается припёка из 10 кг муки
2) 4 : 10 = 0,4 (кг) - получается припёка из 1 кг муки
3) 28 : 0,4 = 70 (кг) - муки нужно взять, чтоб получить 28 кг припёка
4) 70 + 28 = 98 (кг) - хлеба получится из 70 кг муки

Answer 2

Problem Analysis

To solve this problem, we need to determine the weight of the dough and the weight of the flour required to produce a certain amount of bread. We also need to calculate the weight of bread that can be produced from a given amount of flour.

Solution

Let's break down the problem into three parts:

1. Finding the weight of the dough: - From the given information, we know that 10 kg of rye flour produces 14 kg of bread. - To find the weight of the dough, we subtract the weight of the bread from the weight of the flour: 10 kg - 14 kg = -4 kg. - The negative value indicates that the weight of the dough is 4 kg less than the weight of the flour.

2. Finding the weight of flour required to produce 28 kg of bread: - We can use the ratio of bread to flour from the previous calculation to find the weight of flour required. - Since 10 kg of flour produces 14 kg of bread, we can set up a proportion: 10 kg / 14 kg = x kg / 28 kg. - Solving this proportion, we find that x = 20 kg. - Therefore, 20 kg of flour is required to produce 28 kg of bread.

3. Finding the weight of bread produced from 20 kg of flour: - Using the ratio from the previous calculation, we can find the weight of bread produced. - Since 10 kg of flour produces 14 kg of bread, we can set up a proportion: 10 kg / 14 kg = 20 kg / y kg. - Solving this proportion, we find that y = 28 kg. - Therefore, 28 kg of bread can be produced from 20 kg of flour.

Summary

To summarize the solution: - The weight of the dough is -4 kg. - To produce 28 kg of bread, 20 kg of flour is required. - From 20 kg of flour, 28 kg of bread can be produced.
