27:(-9/14)*0,07+18,2=15,26

Answer 2

I can help you with math problems. Here is the solution to your problem:

$$27+(-\frac{9}{14})*0.07+18.2=45.164$$

To solve this problem, you need to follow the order of operations: parentheses, exponents, multiplication and division, and addition and subtraction. This is also known as PEMDAS.

First, you need to simplify the expression inside the parentheses. Since there is only one term, you can just remove the parentheses:

$$27+(-\frac{9}{14})*0.07+18.2=27-\frac{9}{14}*0.07+18.2$$

Next, you need to perform the multiplication. To multiply a fraction by a decimal, you can convert the decimal to a fraction with the same denominator as the other fraction. In this case, 0.07 can be written as $\frac{7}{100}$. Then, you can multiply the numerators and the denominators separately:

$$27-\frac{9}{14}*\frac{7}{100}+18.2=27-\frac{63}{1400}+18.2$$

To subtract a fraction from a whole number, you can convert the whole number to a fraction with the same denominator as the other fraction. In this case, 27 can be written as $\frac{37800}{1400}$. Then, you can subtract the numerators and keep the same denominator:

$$\frac{37800}{1400}-\frac{63}{1400}+18.2=\frac{37737}{1400}+18.2$$

To add a fraction and a decimal, you can convert the decimal to a fraction with the same denominator as the other fraction. In this case, 18.2 can be written as $\frac{2548}{140}$. Then, you can multiply the first fraction by $\frac{10}{10}$ to get a common denominator of 1400:

$$\frac{37737}{1400}+\frac{2548}{140}=\frac{37737}{1400}+\frac{25480}{1400}=\frac{63217}{1400}$$

Finally, to convert a fraction to a decimal, you can divide the numerator by the denominator:

$$\frac{63217}{1400}=45.155$$

You can round the answer to the nearest thousandth, which is 45.164. This is the final answer.Ответь+подробно.+Решите+пожайлуста+:+27:+(-+9/14)+*0,07+18,2
