  1. A rectangular garden is drawn with a length of 125.75 meters and a width of 84.25 meters. What is the total length of fencing needed to go around the entire garden? Answer: 420 Solution: The problem asks for the total length of fencing around a rectangular garden. This means we need to find the perimeter of the rectangle. The formula for the perimeter of a rectangle is P = 2 × (length + width).
    Full step-by-step solution

    Step 1: The problem asks for the total length of fencing around a rectangular garden. This means we need to find the perimeter of the rectangle. Step 2: The formula for the perimeter of a rectangle is P = 2 × (length + width). Step 3: Substitute the given values: length = 125.75 meters, width = 84.25 meters. Step 4: First, add the length and width: 125.75 + 84.25 = 210.00 meters. Step 5: Then multiply by 2: 2 × 210.00 = 420.00 meters. Step 6: The total length of fencing needed is 420 meters.

  2. Mason went to a farm and saw 2957 chickens in the barn. Then Mason saw 6529 chickens in the yard. How many chickens did Mason see in all? Answer: 9486 Solution: Chickens in the barn: 2957. Chickens in the yard: 6529. Add them together: 2957 + 6529 = 9486.
    Full step-by-step solution

    Step 1: Chickens in the barn: 2957. Step 2: Chickens in the yard: 6529. Step 3: Add them together: 2957 + 6529 = 9486. Mason saw 9486 chickens in total.

  3. 3,728 + 4,159 = ? Answer: 7887 Solution: Write the numbers vertically, aligning by place value: 3,728 + 4,159 Add the ones column: 8 + 9 = 17. Write down 7 and carry over 1 to the tens column. Add the tens column: 2 + 5 + 1 (carried over) = 8.
    Full step-by-step solution

    Step 1: Write the numbers vertically, aligning by place value: 3,728 + 4,159 Step 2: Add the ones column: 8 + 9 = 17. Write down 7 and carry over 1 to the tens column. Step 3: Add the tens column: 2 + 5 + 1 (carried over) = 8. Write down 8. Step 4: Add the hundreds column: 7 + 1 = 8. Write down 8. Step 5: Add the thousands column: 3 + 4 = 7. Write down 7. Step 6: The final answer is 7,887.

  4. Nikau went to a farm and saw 6173 chickens in the barn. Then Nikau saw 3226 chickens in the yard. How many chickens did Nikau see in all? Answer: 9399 Solution: Chickens in the barn: 6173. Chickens in the yard: 3226. Add them together: 6173 + 3226 = 9399.
    Full step-by-step solution

    Step 1: Chickens in the barn: 6173. Step 2: Chickens in the yard: 3226. Step 3: Add them together: 6173 + 3226 = 9399. Nikau saw 9399 chickens in total.

  5. A school is organizing a field trip. There are 1,245 students in the morning session and 2,378 students in the afternoon session. How many students are there in total? Answer: 3623 Solution: Write the numbers vertically, aligning the digits by place value. Add the ones column: 5 + 8 = 13. Write down the 3 and carry over the 1 to the tens column.
    Full step-by-step solution

    Step 1: Write the numbers vertically, aligning the digits by place value. Step 2: Add the ones column: 5 + 8 = 13. Write down the 3 and carry over the 1 to the tens column. Step 3: Add the tens column: 1 (carried over) + 4 + 7 = 12. Write down the 2 and carry over the 1 to the hundreds column. Step 4: Add the hundreds column: 1 (carried over) + 2 + 3 = 6. Write down the 6. Step 5: Add the thousands column: 1 + 2 = 3. Write down the 3. Step 6: The final answer is 3,623. The answer is 3623.

  6. Olivia collects stamps. Olivia has 4378 stamps from the United States and 383 stamps from other countries. How many stamps does Olivia have in total? Answer: 4761 Solution: Stamps from the United States: 4378. Stamps from other countries: 383. Add them: 4378 + 383 = 4761.
