Question

(3-2/3):(71/2-1/2)*(1/2+5 1/5-7/10)

Answer 1

Ответ:

1 2/3

Пошаговое объяснение:

3-2/3=7/3

7 1/2-1/2=7

1/2+5 1/5=5/10+5 2/10=5 7/10

5 7/10-7/10=5

7/3/7=(7/7)/3=1/3

1/3*5=(1*5)/3=5/3=1 2/3

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 it down step by step:

1. First, deal with the operations inside the parentheses:

   (3 - 2/3) : (71/2 - 1/2) * (1/2 + 5 1/5 - 7/10)

2. Calculate the values inside the parentheses:

   (9/3 - 2/3) : (35.5 - 0.5) * (0.5 + 5 1/5 - 7/10)

3. Simplify the fractions and subtract within the parentheses:

   (7/3) : (35 - 0.5) * (0.5 + 5 1/5 - 7/10)

4. Continue simplifying within the parentheses:

   (7/3) : (34.5) * (0.5 + 5 1/5 - 7/10)

5. Now, calculate the values inside the innermost parentheses:

   (7/3) : 34.5 * (0.5 + 5 1/5 - 7/10)

6. Simplify further:

   (7/3) : 34.5 * (0.5 + 26/5 - 7/10)

7. Calculate the values within the innermost parentheses:

   (7/3) : 34.5 * (0.5 + 52/10 - 7/10)

8. Continue simplifying:

   (7/3) : 34.5 * (0.5 + 45/10)

9. Calculate the values inside the innermost parentheses:

   (7/3) : 34.5 * (0.5 + 4.5)

10. Simplify further:

(7/3) : 34.5 * 5

11. Calculate the values within the parentheses:

(7/3) : 172.5

12. Finally, perform the division:

(7/3) / 172.5

To simplify further, you can convert 7/3 to a decimal:

(7/3) ≈ 2.3333333

Now, divide:

2.3333333 / 172.5 ≈ 0.0135148

So, the approximate result of the given expression is approximately 0.0135148.
