Lynn wants to multiply 44 x 305. She says that all she has that all she has to do is find 4 x 305 and then double that number. Which explains whether or not Lynn's method will give her the correct answer?

Question

Lynn's method will give her the correct answer. Multiplying by 4 and then doubling the product is the same as multiplying by 44.

Lynn's method will not give her the correct answer. Multiplying by 4 and then doubling the product is same as multiplying by 8, not by 44.

Lynn's method will not give her the correct answer. Multiplying by 4 and then doubling the products is the same as multiplying by 16, not by 44.

Answer 1

Lynn's method will not give her the correct answer. Multiplying by 4 and then doubling the product is the same as multiplying by 8, not by 44.

To explain further:

• Multiplying 4 by 305 gives you \(4 \times 305\).
• Doubling that product means multiplying it by 2, which results in \(2 \times (4 \times 305) = 8 \times 305\).

Thus, Lynn is effectively calculating \(8 \times 305\), which is not the same as \(44 \times 305\). Therefore, her method is incorrect.
