Answer 1

Problem Analysis

The problem states that a total of 18 kg of fruit was collected. Out of this, 3 kg was used to make compote, and the amount used for jam was 4 times greater than the amount used for compote. We need to create different expressions to represent this situation and explain what they mean.

Expressions and Explanations

Let's break down the problem and create the required expressions:

1. Total amount of fruit collected: This is given as 18 kg.

2. Amount of fruit used for compote: This is given as 3 kg.

3. Amount of fruit used for jam: The problem states that the amount used for jam is 4 times greater than the amount used for compote. Therefore, the amount used for jam can be calculated by multiplying the amount used for compote (3 kg) by 4. This can be expressed as: 3 kg * 4 = 12 kg.

4. Remaining amount of fruit: To find the remaining amount of fruit, we need to subtract the amount used for compote and jam from the total amount collected. This can be expressed as: 18 kg - (3 kg + 12 kg) = 18 kg - 15 kg = 3 kg.

To summarize: - Total amount of fruit collected: 18 kg. - Amount of fruit used for compote: 3 kg. - Amount of fruit used for jam: 12 kg. - Remaining amount of fruit: 3 kg.

These expressions represent the different amounts of fruit used for compote, jam, and the remaining amount after using them.
