Answer 1

Ответ:

11\24+5/6=31/24

(31/24)*(48/)=62/5=12,4

Пошаговое объяснение:

11\24+5/6=31/24

(31/24)*(48/)=62/5=12,4

Answer 2

Let's break down the expression step by step:

1. First, simplify the fractions within parentheses: (11/24 + 5/6) = (11/24 + 20/24) = 31/24

2. Next, calculate the expression within the first set of parentheses: -2 + (31/24) = -48/24 + 31/24 = -17/24

3. Now, simplify the mixed numbers: 1 15/16 = (16 + 15)/16 = 31/16 2/5 = 10/16

4. Subtract the fractions within the second set of parentheses: (31/16) - (10/16) = 21/16

5. Finally, divide the result from step 2 by the result from step 4: (-17/24) / (21/16) = (-17/24) * (16/21) = -272/504 = -17/31 (in simplest form)

So, the final result of the expression is -17/31.
