Question

1) (–0,25) ⋅ 3 ⋅ (–4). 2) (–0,2) ⋅ 20 ⋅ (–5) 3) (-4,75) ⋅ 0,2 ⋅ (–2)

Answer 1

Ответ:

Пошаговое объяснение:

1) (–0,25) ⋅ 3 ⋅ (–4)= (-0.25)*(-4)*3= 1*3=3

2) (–0,2) ⋅ 20 ⋅ (–5)=(-0.2)*(-5)*20=1*20=20

3) (-4,75) ⋅ 0,2 ⋅ (–2)=(-4.75)*(-2)*0.2= 9.5*2=19

Answer 2

To evaluate the given expressions, let's calculate them step by step:

1. (–0.25) ⋅ 3 ⋅ (–4) = -0.25 * 3 * -4 = 0.75 * -4 = -3

2. (–0.2) ⋅ 20 ⋅ (–5) = -0.2 * 20 * -5 = 4 * -5 = -20

3. (-4.75) ⋅ 0.2 ⋅ (–2) = -4.75 * 0.2 * -2 = -0.95 * -2 = 1.9

Therefore, the results are:

1. (-0.25) ⋅ 3 ⋅ (-4) = -3
2. (-0.2) ⋅ 20 ⋅ (-5) = -20
3. (-4.75) ⋅ 0.2 ⋅ (-2) = 1.9
