Question

Смесь сухофруктов весит 70 килограммов. Яблоки составляют 5 частей сливы - 2 части массы сухофруктов. Сколько километров яблок и слив в отдельности

Answer 1

Х - одна часть
5х - яблоки
2х - сливы

5х+2х=70
7х=70
х=70:7
х=10 кг - одна часть

10*2=20 кг - слив
10*5=50 кг - яблок 

Answer 2

Calculation of the Weight of Apples and Plums

To calculate the weight of apples and plums separately, we need to use the given ratio of 5 parts apples to 2 parts plum in the total weight of 70 kilograms.

Let's break down the calculation step by step:

1. Determine the weight of one part: - We know that the total weight of the mixture is 70 kilograms. - The ratio of apples to plums is 5:2. - Therefore, the weight of one part is equal to 70 kilograms divided by the sum of the parts in the ratio (5 + 2 = 7).

Weight of one part = 70 kg / 7 = 10 kg

2. Calculate the weight of apples: - The ratio of apples to plums is 5:2. - Since there are 5 parts of apples, we multiply the weight of one part by 5.

Weight of apples = 10 kg/part * 5 parts = 50 kg

3. Calculate the weight of plums: - The ratio of apples to plums is 5:2. - Since there are 2 parts of plums, we multiply the weight of one part by 2.

Weight of plums = 10 kg/part * 2 parts = 20 kg

Therefore, the weight of apples is 50 kilograms and the weight of plums is 20 kilograms.
