Question

Знайти значення виразу ( 3,9 - 5,8 ) - ( - 1/45 - 7/9 ) + 1,1

Answer 1

=-1.9+1/45+7/9+1.1=-0.8+36/45=-0.8+0.8=0

Answer 2

I can help you with your math problem. To find the value of the expression, you need to follow these steps:

1. Simplify the parentheses by adding or subtracting the numbers inside them. For example, $(3.9 - 5.8) = -1.9$ and $(-\frac{1}{45} - \frac{7}{9}) = -\frac{29}{45}$. 2. Subtract the second parenthesis from the first one. For example, $(-1.9) - (-\frac{29}{45}) = -1.9 + \frac{29}{45}$. 3. Add 1.1 to the result of step 2. For example, $-1.9 + \frac{29}{45} + 1.1 = -0.8 + \frac{29}{45}$. 4. Convert the mixed number to an improper fraction by multiplying the whole part by the denominator and adding the numerator. For example, $-0.8 + \frac{29}{45} = -\frac{36}{45} + \frac{29}{45}$. 5. Add the fractions by finding the common denominator and adding the numerators. For example, $-\frac{36}{45} + \frac{29}{45} = \frac{-36 + 29}{45} = -\frac{7}{45}$.

The final answer is $-\frac{7}{45}$. You can check your answer by plugging it back into the original expression and simplifying it. You should get zero as the result.
