Question

(-106)+(8,2)×(25/41);(-1)+(-0,85)×(16/17

Answer 1

Ответ:

Пошаговое объяснение:

(-106)+(8,2)×(25/41)=-101

8.2*25\41=41\5*25\41=5

-106+5=-101

(-1)+(-0,85)×(16/17)=-1 4\5

-0.85*16\17=-17\20*16\17=-4\5

-1+(-4\5)=-1 4\5

Answer 2

To calculate the given expressions:

1. (-106) + (8,2) × (25/41):

First, let's simplify the multiplication: (8.2) × (25/41) = (205/25) × (25/41) = 5125/1025.

Now, let's add -106 to the result: -106 + (5125/1025).

To perform the addition, we need to find a common denominator for -106 and 1025, which is 1025.

Converting -106 to have a denominator of 1025: (-106 × 1025)/1025 = -108,650/1025.

Now we can add the fractions: (-108,650/1025) + (5125/1025) = (-108,650 + 5125)/1025 = -103,525/1025.

The final result is -103,525/1025.

2. (-1) + (-0.85) × (16/17):

First, let's simplify the multiplication: (-0.85) × (16/17) = (-0.85 × 16)/(17) = (-13.6)/17.

Now, let's add -1 to the result: -1 + (-13.6/17).

To perform the addition, we need to find a common denominator for -1 and 17, which is 17.

Converting -1 to have a denominator of 17: (-1 × 17)/17 = -17/17.

Now we can add the fractions: (-17/17) + (-13.6/17) = (-17 - 13.6)/17 = (-30.6)/17.

The final result is -30.6/17.
