Question

(5/6 * 5 - 5) : 2/3 - 0,5(В квадрате)=

Answer 1

Ответ:

Пошаговое объяснение:

5/6*5=25/6=4 1/6

4 1/6-5=-5/6

-5/6:2/3=-5/6*3/2=-5/4=-1,25

-1,25-0,5^2 =-1,25-0,25=-1,5

Answer 2

1) 5/6 * 5 = 25/6
2) 25/6 - 5 = 25/6 - 30/6 = - 5/6
3) -5/6 : 2/3 = -5/6 * 3/2 = -5/4
4) -5/4 - 0.5² = -5/4 - 0.25 = -5/4 - 1/4 = -6/4 = -3/2

Answer 3

Let's simplify the expression step by step:

1. First, calculate the value inside the parentheses: (5/6 * 5 - 5). (5/6 * 5) = 25/6 Now, (25/6 - 5) = (25/6 - 30/6) = -5/6

2. Next, divide the result by the fraction 2/3: (-5/6) ÷ (2/3) = (-5/6) * (3/2) = -5/4

3. Now, let's calculate 0.5 squared: 0.5^2 = 0.5 * 0.5 = 0.25

4. Finally, subtract the squared value from the previous result: -5/4 - 0.25 = -5/4 - 1/4 = -6/4 = -3/2

So, the simplified expression is: -3/2.
