Answer 1

Ответ:

113/110

Пошаговое объяснение:

7/5+9/10*9/10(31/15+49/50/(-49/120))

7/5+9/10*9/10(31/15-49/50*120/49)

7/5+9/10*9/10(31/15-12/5)

7/5+9/10*9/10(-1/3)

7/5-3/10*9/10

Answer 2

To solve the expression, let's break it down step by step:

1. Calculate the expression inside the parentheses: 3 1/15 + 0,98 : (12/65 - 7/52 - 11/24)

   To simplify the expression, we need to perform the operations in the following order: first division, then subtraction, and finally addition.

   12/65 - 7/52 - 11/24: To perform this subtraction, we need to find a common denominator. The common denominator for 65, 52, and 24 is 3120.

   (12/65 * 48/48) - (7/52 * 60/60) - (11/24 * 130/130) = (576/3120) - (420/3120) - (1430/3120) = (576 - 420 - 1430) / 3120 = (-1274) / 3120

   Now we can simplify the addition inside the parentheses: 3 1/15 + 0.98 : (-1274/3120) = (46/15 + 0.98) : (-1274/3120)

2. Multiply 0.9 by 0.9: 0.9 * 0.9 = 0.81

3. Divide 0.98 by (-1274/3120): 0.98 : (-1274/3120) = 0.98 * (3120/-1274)

4. Add 3 1/15 to 0.98 * (3120/-1274): (46/15 + 0.98) * (3120/-1274)

5. Multiply the result from step 4 by 0.81: (46/15 + 0.98) * (3120/-1274) * 0.81

6. Add 1.4 to the result from step 5: 1.4 + (46/15 + 0.98) * (3120/-1274) * 0.81

Now, you can evaluate the expression using a calculator or perform the calculations step by step to get the final result.
