Question

(-2/1+5/1)+(2,7-2,8)-1,05​

Answer 1

Ответ: 1,85

Пошаговое объяснение:

( - 2/1 + 5/1 ) + ( 2,7 - 2,8 ) - 1,05 = ( - 2 + 5 ) + ( - 0,1) - 1,05 = 3 - 0,1 - 1,05 = 2,9 - 1,05 = 1,85

Answer 2

It seems like you're providing a mathematical expression for evaluation. Let's solve it step by step:

(-2/1 + 5/1) + (2.7 - 2.8) - 1.05

First, simplify the fractions: -2/1 + 5/1 = -2 + 5 = 3

Now, subtract the decimals: 2.7 - 2.8 = -0.1

Now, substitute these values back into the original expression: 3 + (-0.1) - 1.05

Combine the numbers: 3 - 0.1 - 1.05 = 1.85

So, the result of the expression is 1.85.
