Question

( - 4/27 + ( 0,75 ) : ( - 3/4 ) - 3 1/3 : ( - 1,5 ) ) ( - 1 7/20 )

Answer 1

Ответ:

Пошаговое объяснение:

(-4,5)^2:(-0,75)-3,4=(-4,5)*(-4,5):(-0,75)-3,4=20,25:(-0,75)-3,4=

-27-3,4=-30,4

Answer 2

To simplify the given expression, follow the order of operations (PEMDAS/BODMAS):

P: Parentheses first E: Exponents (none in this expression) MD: Multiplication and Division (from left to right) AS: Addition and Subtraction (from left to right)

Step 1: Solve the expression inside the innermost parentheses.

diffCopy code
- 3/4 = -0.75
- 1.5 = -1.5

Step 2: Perform the divisions first.

scssCopy code
0.75 / -0.75 = -1
(-3 1/3) / (-1.5) = 2.22 (rounded to two decimal places)

Step 3: Replace the divisions with the results from Step 2:

diffCopy code
- 4/27 + (-1) - 2.22

Step 4: Now perform the addition and subtraction operations from left to right:

diffCopy code
- 4/27 + (-1) = -4/27 - 27/27 = -31/27
- 31/27 - 2.22 ≈ -2.85 (rounded to two decimal places)

Step 5: Finally, multiply the result by -1 7/20:

scssCopy code
-1 7/20 = -27/20

(-2.85) * (-27/20) = 3.8175 (rounded to four decimal places)

So, the simplified value of the given expression is approximately 3.8175.
