Carly claims that multiplication always makes a number bigger. He gave the following examples:
If I take 6, and I multiply it by 4, I get 24, which is bigger than 6.
If I take 14, and I multiply it by 2 (whole number), I get 24, or 12, which is bigger than 14.
Carly’s reasoning is incorrect. Give an example that proves she is wrong, and explain her mistake using pictures, words, or numbers.
Answers will vary, basic premise is that multiplying by a fraction is going to get a piece of the factor being multiplied.
