Question

1 simplify 2.4(-3.3 - 0.9 + 1.2).

Explanation:

Step1: Simplify inside the parentheses

First, calculate the value inside the parentheses: $-3.3 - 0.9 + 1.2$.
$-3.3 - 0.9 = -4.2$, then $-4.2 + 1.2 = -3$.

Step2: Multiply by 2.4

Now, multiply the result by 2.4: $2.4\times(-3)$.
$2.4\times(-3) = -7.2$.

Answer:

$-7.2$
