Question

Elaine writes (3 × 9) × 22 and then plans to find the exact area of the canvas using the Associative Property. How can she do this and only multiply by a 1-digit number?

Answer 1

Explanation:

Elaine can use the Associative Property to find the exact area of the canvas by multiplying the numbers in a different order. The Associative Property states that the grouping of numbers being multiplied does not affect the product.

To multiply by a 1-digit number, Elaine can first multiply 3 by 9, which equals 27. Then, she can multiply 27 by 22. By multiplying the two numbers in this order, she is only multiplying by a 1-digit number.

Let's break it down step-by-step:

1. Start with the expression (3 × 9) × 22.

2. Multiply 3 by 9, which equals 27.

3. Rewrite the expression as 27 × 22.

4. Multiply 27 by 22 to find the exact area of the canvas.

By rearranging the numbers and using the Associative Property, Elaine can find the area of the canvas by only multiplying by a 1-digit number.
