Answer 1

штоб нам все ето узнать над усе звести до общего числа тоист до 24

и у нас получица так

2 18/24 -(- 1 12/24)+(-20/24)-(-9/24)- 4 16/24=7 75/24=10 3/24=10 1/8

Answer 2

To solve the expression 2 3/4 - (-1 1/2) + (-5/6) - (-3/8) - 4 2/3, we need to perform the operations in the correct order. Let's break it down step by step:

Step 1: Simplify the mixed numbers and fractions: 2 3/4 = 11/4 -1 1/2 = -3/2 4 2/3 = 14/3

Now the expression becomes: 11/4 - (-3/2) + (-5/6) - (-3/8) - 14/3

Step 2: Apply the operation of subtracting a negative number, which is equivalent to adding a positive number: 11/4 + 3/2 + (-5/6) + 3/8 - 14/3

Step 3: Find a common denominator for the fractions: The common denominator for 4, 2, 6, 8, and 3 is 24.

11/4 becomes 66/24 3/2 becomes 36/24 -5/6 remains -5/6 3/8 becomes 9/24 -14/3 becomes -112/24

The expression now becomes: 66/24 + 36/24 - 5/6 + 9/24 - 112/24

Step 4: Add and subtract the fractions: (66 + 36 - 5 + 9 - 112)/24

Combine the numerators: (66 + 36 - 5 + 9 - 112) = -6

The expression simplifies to: -6/24

Step 5: Simplify the fraction: -6/24 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 6: -6/24 = -1/4

Therefore, the expression 2 3/4 - (-1 1/2) + (-5/6) - (-3/8) - 4 2/3 simplifies to -1/4.
