Answer 3

I can help you with math problems. Here is the detailed solution for your expressions:

а) $$87619 + \frac{57994}{271} - \frac{15975}{75}$$

To solve this expression, we need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction (PEMDAS).

First, we simplify the fractions by dividing the numerator by the denominator:

$$\frac{57994}{271} \approx 213.9963$$ $$\frac{15975}{75} = 213$$

Then, we perform the addition and subtraction from left to right:

$$87619 + 213.9963 - 213 = 87619.9963 - 213$$ $$= 87406.9963$$

The final answer is:

$$87619 + \frac{57994}{271} - \frac{15975}{75} \approx 87406.9963$$

б) $$532 \times 109 - 48016 + \frac{13631}{43}$$

To solve this expression, we also need to follow the order of operations (PEMDAS).

First, we simplify the fraction by dividing the numerator by the denominator:

$$\frac{13631}{43} \approx 316.7674$$

Then, we perform the multiplication and division from left to right:

$$532 \times 109 = 57988$$

Then, we perform the addition and subtraction from left to right:

$$57988 - 48016 + 316.7674 = 9988 + 316.7674$$ $$= 10304.7674$$

The final answer is:

$$532 \times 109 - 48016 + \frac{13631}{43} \approx 10304.7674$$

I hope this helps you understand how to solve these expressions. If you have any more questions, feel free to ask me.
