Answer 3

Let's break down the expression step by step:

First, let's simplify the arithmetic expression (-1/8 + 1/5):

To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 40. Converting the fractions to have a denominator of 40, we get:

(-1/8) = (-1/8) * (5/5) = -5/40 (1/5) = (1/5) * (8/8) = 8/40

Now, we can add the fractions:

(-5/40 + 8/40) = 3/40

So (-1/8 + 1/5) simplifies to 3/40.

Next, let's simplify the expression (4, 8-4, 9):

This expression appears to be a list of numbers separated by commas. To evaluate it, we can simply take the last number in the list:

(4, 8-4, 9) = 9

Finally, let's subtract 2.05 from the previous result:

9 - 2.05 = 6.95

Therefore, the simplified expression (-1/8 + 1/5) - (4, 8-4, 9) - 2.05 is equal to 6.95.
