Question

0,25×{0,25÷[(2,5-0,3-1,75):0,5]}

Answer 1

Ответ:

5/72

Пошаговое объяснение:

0,25×{0,25÷[(2,5-0,3-1,75):0,5]} = 0,25×{0,25÷[0,45:0,5]} = 0,25×{0,25÷0.9} =

1/4*{1/4÷9/10} = 1/4*1/4*10/9=5/72

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 the expression step by step:

1. Start with the innermost parentheses:

   (2,5 - 0,3 - 1,75) = 0,45

2. Now, divide 0,45 by 0,5:

   0,45 ÷ 0,5 = 0,9

3. Next, calculate the product of 0,25 and 0,9:

   0,25 × 0,9 = 0,225

So, the result of the expression is 0,225.
