Answer 1

Ответ:

36 82/90

Пошаговое объяснение:

Сначала в скобках будет 36 и 5/9  - 5.2 =  переводим 36 5/9 и 5 2/10 = 36 50/90 - 5 18/90 = 31 32/90

и + 5 5/9 получаеться 31 32/90+5 5/9 = переводим 31 32/90+5 50/90 =36 82/90

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Perform the operations inside the parentheses first.
2. Then, deal with addition and subtraction from left to right.

Let's solve it step by step:

Step 1: Operations inside the parentheses 39 - 2 = 37 2 4/9 = 2 + 4/9 = (18 + 4)/9 = 22/9

So, the expression inside the parentheses becomes: 37 - 22/9

Step 2: Add the fractions 5 + 5/9 = (45/9) + 5/9 = 50/9

Now, the whole expression becomes: 5, 2 - (37 - 22/9) + 50/9

Step 3: Subtract the expression inside the parentheses 37 - 22/9 = (333/9) - (22/9) = 311/9

Now, the whole expression becomes: 5, 2 - 311/9 + 50/9

Step 4: Add the whole number and fractions 5 + 2 = 7

Now, the whole expression becomes: 7 - 311/9 + 50/9

Step 5: Combine the fractions (311/9) + (50/9) = 361/9

Now, the whole expression becomes: 7 - 361/9

Step 6: Convert 7 to a fraction with a common denominator of 9 7 = 63/9

Now, the whole expression becomes: 63/9 - 361/9

Step 7: Perform the subtraction (63/9) - (361/9) = (63 - 361)/9 = (-298)/9

The final result is: -298/9 or approximately -33.11 (rounded to two decimal places).
