1) 4 23\30-2,55=4 23\30-2 55\100=4 23\30-2 11\20=4 46\60-2 33\60=2 13\60

2) -82-2 13\60=-84 13\60

Answer 2

To simplify this expression, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

So, starting from the innermost parentheses:

• 4 23/30 - 2,55 = 4.76666666667 - 2.55 = 2.21666666667

Now we can substitute this value back into the original expression:

-82 - 2.21666666667 = -84.2166666667

Therefore, the simplified value of the expression -82-(4 23/30 - 2.55) is approximately equal to -84.2167.
