Answer:

Emanuel did a mistake in her first step.

Step-by-step explanation:

The given expression is

\left(\dfrac{3}{5}\right)\left(\dfrac{4}{9}\right)\left(-\dfrac{1}{2}\right)

Emanuel solve this problem but she did a mistake in her first step. She distributes negative sign with 1 and 2 both which is incorrect. We can write negative sign with either 1 or 2 but not both.

Correct steps are:

Step 1:

\dfrac{(3)(4)(-1)}{(5)(9)(2)}

Step 2:

\dfrac{-12}{90}

Step 3:

-\dfrac{2}{15}

Therefore, she did a mistake in her first step.
