Answer 1

Ответ:

5

Пошаговое объяснение:

1) 5 × 19/14 - 4/3 × 75/56 (Сокращаем дробь и вычисляем)

2) 95/14 - 25/14 (Вычитаем дроби)

Answer 2

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

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's proceed step by step:

Step 1: Solve the expression inside the parentheses. 9/14 + 5/7 = (91)/(141) + (52)/(72) = 9/14 + 10/14 = (9 + 10)/14 = 19/14

Step 2: Calculate the multiplication and division from left to right. 5 * (19/14) = 95/14

Step 3: Solve the division. 1 ÷ (3/4) = 1 * (4/3) = 4/3

Step 4: Solve the multiplication. (4/3) * (75/56) = (475)/(356) = 300/168 = 25/14

Step 5: Final calculation of the expression. 95/14 - 25/14 = (95 - 25)/14 = 70/14 = 5

So, the final answer is 5.
