Answer 2

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

First, we need to simplify the fractions in the expression. We can do this by finding the common denominator and adding the numerators.

$$a = 2 + \frac{1}{7} = \frac{14}{7} + \frac{1}{7} = \frac{15}{7}$$

$$b = 1 + \frac{1}{7} = \frac{7}{7} + \frac{1}{7} = \frac{8}{7}$$

$$\frac{3}{4} = \frac{21}{28}$$

Next, we can substitute the values of $a$ and $b$ into the expression and use the distributive property to multiply.

$$8 + \frac{3}{4}(a + b) = 8 + \frac{21}{28}(a + b) = 8 + \frac{21}{28}a + \frac{21}{28}b$$

$$= 8 + \frac{21}{28} \cdot \frac{15}{7} + \frac{21}{28} \cdot \frac{8}{7} = 8 + \frac{45}{28} + \frac{24}{28}$$

Finally, we can add the fractions and the whole number by finding the common denominator and adding the numerators.

$$8 + \frac{45}{28} + \frac{24}{28} = \frac{224}{28} + \frac{69}{28} = \frac{293}{28}$$

Therefore, the value of the expression is $\frac{293}{28}$.Ответь+подробно.+Найдите+значенип+выражения+8+3/4(a+b)+если+a+=2+1/7+b=1+1/7
