Question

2 7/10-2,03•(-6,75):2,25-6,12:(1 1/3-(-2 2/3)-3,25)

Answer 1

Ответ:

0,63

Пошаговое объяснение:

2,03*(-6,75)= -13,7025

-13,7025:2,25= -6,09

1 1/3+2 2/3=3 3/3=4

4-3,25=0,75

6,12:0,75=8,16

2,7-(-6,09)=2,7+6,09=8,79

8,79-8,16=0,63

Answer 2

Let's break down the expression step by step:

Step 1: Simplify the subtraction and multiplication first.

2 7/10 - 2,03 • (-6,75) : 2,25 - 6,12 : (1 1/3 - (-2 2/3) - 3,25)

Step 2: Perform the subtraction and multiplication:

Convert mixed numbers to improper fractions: 2 7/10 = 2 + 7/10 = 27/10 1 1/3 = 1 + 1/3 = 4/3 -2 2/3 = -2 - 2/3 = -8/3

Now, the expression becomes:

27/10 - 2.03 • (-6.75) : 2.25 - 6.12 : (4/3 - (-8/3) - 3.25)

Step 3: Continue with multiplication and division:

27/10 + 2.03 • 6.75 : 2.25 - 6.12 : (4/3 + 8/3 - 3.25)

Step 4: Perform the multiplication:

27/10 + 13.7025 : 2.25 - 6.12 : (4/3 + 8/3 - 3.25)

Step 5: Perform the division:

27/10 + 13.7025 : -3.87 : (4/3 + 8/3 - 3.25)

Step 6: Simplify inside the parentheses:

27/10 + 13.7025 : -3.87 : (4/3 + 8/3 - 3.25) = 27/10 + 13.7025 : -3.87 : (9/3 - 3.25)

Step 7: Perform addition and subtraction inside the parentheses:

27/10 + 13.7025 : -3.87 : (9/3 - 3.25) = 27/10 + 13.7025 : -3.87 : (3 - 3.25) = 27/10 + 13.7025 : -3.87 : (-0.25)

Step 8: Continue with division:

27/10 + 13.7025 : -3.87 : (-0.25) = 27/10 + 13.7025 : 15.48

Step 9: Perform the final division:

27/10 + 0.881393: 15.48 ≈ 27/10 + 0.05686 ≈ 27/10 + 0.5686

Step 10: Convert the result to a mixed number:

27/10 + 0.5686 = 27/10 + 5.686/10 = (27 + 5.686)/10 = 32.686/10 ≈ 3.2686

So, the final result of the expression is approximately 3.2686.
