Answer 1

Ответ:

$\frac{2}{7}$

Пошаговое объяснение:

$\frac{7}{6} +\frac{8}{49} :(3-2\frac{23}{35} )-1\frac{5}{14} =\frac{7}{6} +\frac{8}{49} :\frac{12}{35} -1\frac{5}{14} =\frac{7}{6} +\frac{10}{21} -1\frac{5}{14} =\frac{23}{14} -1\frac{5}{14} =1\frac{9}{14} -1\frac{5}{14} =\frac{4}{14} =\frac{2}{7}$

Answer 2

To solve the expression, let's follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

1. Resolve the expression inside the parentheses: 3 - 2 23/35 = 3 - 2.6571... ≈ 0.3429...

2. Perform the division inside the parentheses: 8/49 ÷ 0.3429... ≈ 1.1707...

3. Resolve the division outside the parentheses: 7/6 ÷ 1.1707... ≈ 1.1957...

4. Subtract 1 5/14: 1.1957... - 1 5/14 = 1.1957... - 1.3571... ≈ -0.1614...

So, the result is approximately -0.1614.
