Question

(−27,34+(−1,1))+(−1/5+(−1/25))

Answer 1

(−27,34+(−1,1))+(−1/5+(−1/25))=(-27,34-1,1)+(-0,2-0,04)=-28,44-0,24=-28,68

Answer 2

To solve the expression (−27,34 + (−1,1)) + (−1/5 + (−1/25)), let's simplify it step by step:

First, let's simplify the innermost parentheses: −27,34 + (−1,1) = −28,44

The expression now becomes: (−28,44) + (−1/5 + (−1/25))

Next, let's simplify the addition of fractions: −1/5 + (−1/25) = −5/25 + (−1/25) = −6/25

The expression now becomes: (−28,44) + (−6/25)

To add a decimal number to a fraction, we need to convert the decimal to a fraction with the same denominator as the fraction. Since the fraction already has a denominator of 25, we'll convert −28,44 to a fraction with a denominator of 25: −28,44 = −2844/100 = −1422/50

Now, we can rewrite the expression as: (−1422/50) + (−6/25)

To add fractions, we need to have a common denominator. In this case, the common denominator is 50. Let's convert the fractions: −1422/50 + (−6/25) = −2844/100 + (−4/50)

Now, the expression becomes: (−2844/100) + (−4/50)

To add fractions with the same denominator, we can simply add their numerators while keeping the denominator the same: (−2844/100) + (−4/50) = (−2844 − 4)/100 = −2848/100

Finally, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 4: −2848/100 = −712/25

Therefore, the simplified expression is −712/25.
