Question

2,5(-4)+(-6,3):(-2,1)

Answer 1

2,5*(-4)=10

(-6,3):(-2,1)=3

10+3=13

Answer 2

Let's break down the expression step by step:

1. 2,5(-4): Multiply 2,5 by -4. $2,5 \times (-4) = -10$

2. (-6,3):(-2,1): Divide -6,3 by -2,1. $\frac{-6,3}{-2,1} = 3$

3. Add the results: $-10 + 3 = -7$

So, $2,5(-4) + (-6,3):(-2,1) = -7$.
