Answer 2

Problem Analysis

We are given that 42 kg of flour was used in a bakery kiosk over a period of 7 days. We need to find out how much flour was used in 4 days if the flour was used evenly each day.

Solution

To solve this problem, we can set up a proportion using the given information. Let's denote the amount of flour used in 4 days as 'x' kg. We can set up the following proportion:

7 days : 42 kg = 4 days : x kg

To find 'x', we can cross-multiply and solve for 'x':

7 * x = 4 * 42

Now, let's calculate the value of 'x':

x = (4 * 42) / 7

x = 24 kg

Therefore, 24 kg of flour was used in 4 days.

Table and Expression

| Days | Flour Used (kg) | |------|-----------------| | 7 | 42 | | 4 | x |

Expression: 7 days : 42 kg = 4 days : x kg

Solution

To find the value of 'x', we can cross-multiply and solve for 'x':

7 * x = 4 * 42

x = (4 * 42) / 7

x = 24 kg

Therefore, 24 kg of flour was used in 4 days.
