Question

(3,5+1/4)⋅1,2(7,6−7 2/5):2/3

Answer 1

Ответ:

27/20 или 1 7/20 или 1,35

Пошаговое объяснение:

Я знаю, это правильно.

(3,5+1/4)*1,2(7,6-7 2/5):2/3=(7/2+1/4)*6/5*(38/5-37/5)*3/2=15/4*3/5*1/5*3=3/4*3*1/5*3=27/20

Так и всё

Answer 2

To solve this expression, you can follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) to simplify it step by step:

1. First, calculate the expression inside the parentheses: 5 + 1/4 = 5.25

2. Next, calculate the expression inside the brackets: 7.6 - 7 2/5 = 7.6 - 7.4 = 0.2

3. Now, you can rewrite the expression with the results: (3, 5.25) * 1.2 * (0.2) / (2/3)

4. Perform the multiplications: 3 * 5.25 = 15.75 15.75 * 1.2 = 18.9 18.9 * 0.2 = 3.78

5. Finally, divide by 2/3 (which is the same as multiplying by 3/2): 3.78 * (3/2) = 5.67

So, the result of the expression is 5.67.
