Final answer:
Leanne is incorrect. When multiplying 8 times 4.3, the correct product is 34.4, not 32.24.
Explanation:
Leanne is incorrect. When multiplying 8 times 4.3, the correct product is 34.4, not 32.24. To explain this, let's use an area model.
Step-by-step explanation:
Draw a rectangle to represent 8 units long and 4.3 units wide.
Divide the rectangle into smaller squares or rectangles.
Count the number of smaller squares or rectangles in the area model.
In this case, we can divide the rectangle into 8 columns and 10 rows, resulting in 80 smaller squares or rectangles.
Each smaller square or rectangle represents a product of 1 times 0.1, so to find the total area, we multiply 80 by the product of 1 times 0.1.
80 multiplied by 0.1 equals 8, so the total area is 8 square units.
Therefore, the correct answer is 34.4, not 32.24

Final answer:
Leanne's calculation of 8 times 4.3 is incorrect. Using an area model, the correct answer is found to be 34.4, not 32.24.
Explanation:
Leanne's result of multiplying 8 times 4.3 to get 32.24 is not correct. To demonstrate this, we can use an area model to correct the multiplication.
An area model involves breaking up the factors into more manageable numbers, multiplying them separately, and then adding the results together. In this case, we can consider 4.3 as 4 + 0.3 to simplify the multiplication process.
Multiply the whole number part: 8 × 4 = 32.
Multiply the decimal part: 8 × 0.3 = 2.4.
Add both parts together: 32 + 2.4 = 34.4.
So, the correct answer of 8 × 4.3 is 34.4, not 32.24.
