Пошаговое объяснение:

$\frac{11}{4}+\frac{3}{2}-\frac{5}{6}-\frac{3}{8}-\frac{14}{3}=\\\\=\frac{66+36-20-9-112}{24}=-\frac{39}{24}=-\frac{13}{8}=-1,625$

Answer 2

Calculating the Expression

To solve the given expression, we can follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) to simplify it step by step.

First, let's solve the expression: 2¾ - (-1½) + (-⅚) - (⅜) - 4⅔.

1. Convert Mixed Numbers to Improper Fractions: - 2¾ = 11/4 - -1½ = -3/2 - -⅚ = -6/9 = -2/3 - ⅜ = 3/8 - 4⅔ = 14/3

2. Apply the Minus Sign: - 2¾ - (-1½) + (-⅚) - (⅜) - 4⅔ becomes 11/4 + 3/2 - 2/3 - 3/8 - 14/3

3. Find a Common Denominator: - The common denominator for 4, 2, 3, 8, and 3 is 24.

4. Perform the Operations: - 11/4 = 66/24 - 3/2 = 36/24 - 2/3 = 16/24 - 3/8 = 9/24 - 14/3 = 112/24

5. Combine the Fractions: - 66/24 + 36/24 - 16/24 - 9/24 - 112/24 = (66 + 36 - 16 - 9 - 112)/24 = -35/24

Final Answer

The value of the expression 2¾ - (-1½) + (-⅚) - (⅜) - 4⅔ is -35/24.
