Question

1. Provide a counterexample that shows the statement is false. Explain why the counterexample makes the statement false.

If two fractions have unlike denominators, then the LCD is the product of their denominators.

Answer 1

Will give medal for person with best response :)

Answer 2

well actually the least common denominator is when you do the factor tree to get the least common denominator say if i had 1/2 + 4/6 the least common denominator would not be 12 it would be 6

Answer 3

hints:
1. Question asks you to provide a counter example, so you need to show an example where the product is not equal to the LCM. No mathematical proof is required, but you need to explain how the example is contradicting the given statement.
2. the product IS the LCM when the two denominators are coprime (i.e. have no common factors). What happens when...
