Task for 4th Grade: Dishwashing and Dining Room Cleaning

To determine the number of children needed for dishwashing, we are given that 6 children are required for both dishwashing and cleaning the dining room. Additionally, it is mentioned that the number of children needed for dishwashing is half the number needed for cleaning the dining room. Let's calculate the number of children needed for dishwashing.

Step 1: Define the Number of Children for Cleaning the Dining Room - Let's assume the number of children needed for cleaning the dining room is represented by x.

Step 2: Calculate the Number of Children for Dishwashing - As per the given information, the number of children needed for dishwashing is half the number needed for cleaning the dining room, which can be represented as x/2.

Step 3: Total Number of Children - The total number of children needed for both tasks is 6, so we can write the equation: x + x/2 = 6.

Step 4: Solve for x - To find the value of x, we can solve the equation x + x/2 = 6.

Step 5: Calculate the Number of Children for Dishwashing - Once we find the value of x, we can calculate the number of children needed for dishwashing, which is x/2.

Let's solve the equation to find the number of children needed for dishwashing.

Solution

- Step 1: Define the Number of Children for Cleaning the Dining Room - Let's assume the number of children needed for cleaning the dining room is represented by x.

- Step 2: Calculate the Number of Children for Dishwashing - The number of children needed for dishwashing is half the number needed for cleaning the dining room, which can be represented as x/2.

- Step 3: Total Number of Children - The total number of children needed for both tasks is 6, so we can write the equation: x + x/2 = 6.

- Step 4: Solve for x - To find the value of x, we can solve the equation x + x/2 = 6.

- Step 5: Calculate the Number of Children for Dishwashing - Once we find the value of x, we can calculate the number of children needed for dishwashing, which is x/2.

Calculation

- Solving the equation x + x/2 = 6: - Multiplying the entire equation by 2 to clear the fraction: 2x + x = 12 - Combining like terms: 3x = 12 - Dividing by 3: x = 4

Answer

- Number of Children Needed for Dishwashing: 4

Therefore, 4 children are needed for dishwashing.
