Lynn wants to multiply 44 x 305. She says 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 the same as multiplying by 6, not by 44.

Lynn's method will not give her the correct answer. Multiplying by 4 and then doubling the product is the same as Multiplying by 4 and then doubling the product 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 clarify:

• When Lynn multiplies \(4 \times 305\), she gets \(1220\).
• When she doubles that result, \(1220 \times 2\) equals \(2440\).
• However, the correct product of \(44 \times 305\) should be \(13420\).

Thus, her method is incorrect as it is not equivalent to multiplying by 44.
