Пошаговое объяснение:

=-81,3+3 11/16-9,9+11 5/16=-81,3-9,9+(3 11/16+11 5/16)=-81,3-9,9+15=-76,2

Answer 2

-(81,3-3 11/16)-(9,9-11 5/16)

-(183/10-33/16)-(99/10-55/16)

-1299/80-517/80

-227/10

Answer 3

To simplify the expression, let's perform the subtraction and simplify the fractions:

(81,3-3 11/16) - (9,9-11 5/16)

81,3 is the same as 81 + 3/10. 3 11/16 is the same as 3 + 11/16. 9,9 is the same as 9 + 9/10. 11 5/16 is the same as 11 + 5/16.

Now, we can rewrite the expression as:

(81 + 3/10) - (9 + 9/10 - 11 - 5/16)

Simplifying further:

81 + 3/10 - 9 - 9/10 + 11 + 5/16

Combine like terms:

81 - 9 + 11 + 3/10 - 9/10 + 5/16

Perform the subtraction:

(81 - 9 + 11) + (3/10 - 9/10 + 5/16)

Combine like terms:

83 + (3/10 - 9/10 + 5/16)

Perform the subtraction and simplify the fractions:

83 + (-6/10 + 5/16)

Convert the fractions to have a common denominator:

83 + (-96/160 + 50/160)

Combine the fractions:

83 + (-46/160)

Simplify the fraction:

83 - 46/160

Convert the mixed number back to an improper fraction:

83 - (46/160)

Subtract the fractions:

83 - 46/160 = (83 * 160 - 46) / 160 = (13280 - 46) / 160 = 13234/160

Simplify the fraction if possible:

13234/160 = 827/10

Therefore, -(81,3-3 11/16)-(9,9-11 5/16) simplifies to -827/10.
