Question

8) 4/5 • 15,7 + 16,995 : 3,09 - 8 16/3​

Answer 1

Ответ:

9,8725

Пошаговое объяснение:

1) 4/5 * 15,7 = 0,8 * 15,7 = 12,56

2) 16,995 : 3,09 = 5,5

3) 12,56 + 5,5 = 18,06

4) 18,06 - 8 3/16 = 18,06 - 8,1875 = 9,8725

Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). Let's break down your expression step by step:

1. Perform division first: 4/5 • 15.7 + 16.995 / 3.09 - 8 16/3

2. Calculate the divisions: (4/5) • 15.7 + (16.995 / 3.09) - (8 16/3)

3. Calculate the multiplications: (0.8) • 15.7 + (5.50406504) - (8 16/3)

4. Now, deal with the remaining multiplication: 12.56 + 5.50406504 - (8 16/3)

5. Finally, perform the last multiplication: 12.56 + 5.50406504 - (42.66666667)

6. Now, subtract the result of the last multiplication from the sum of the previous two numbers: 12.56 + 5.50406504 - 42.66666667

7. Perform the addition and subtraction from left to right: (12.56 + 5.50406504) - 42.66666667 18.06406504 - 42.66666667

8. Finally, subtract the two results: -24.60260163

So, the result of the expression is approximately -24.60260163.
