(Three-fifths) (StartFraction 4 over 9 EndFraction) (Negative one-half) Step 1 StartFraction (3) (4) (negative 1) over (5) (9) (negative 2) EndFraction Step 2 StartFraction negative 12 over negative 90 EndFraction Step 3 StartFraction 12 over 90 EndFraction Step 4 StartFraction 2 over 15 EndFraction In which step did his first error occur? help asap

Answer 1

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.
