Answer 1

Ответ на этот пример 0,59

Answer 2

To solve this expression step by step, you should follow the order of operations (PEMDAS/BODMAS):

1. First, simplify within parentheses or brackets if applicable.
2. Then, perform any multiplication or division from left to right.
3. Finally, perform any addition or subtraction from left to right.

Let's break down your expression step by step:

0.64 - 1/25 / 0.8 : (4/5 * 1.25)

1. Start with the division inside the parentheses:

   4/5 * 1.25 = 5/5 = 1

2. Now, substitute the result back into the expression:

   0.64 - 1/25 / 0.8 : 1

3. Perform the division on the left side:

   1/25 / 0.8 = (1/25) / (4/5)

   To divide by a fraction, you multiply by its reciprocal:

   (1/25) / (4/5) = (1/25) * (5/4) = 5/100 = 1/20

4. Substitute the result back into the expression:

   0.64 - 1/20 : 1

5. Perform the subtraction:

   0.64 - 1/20 = 0.64 - 0.05 = 0.59

So, the final result is 0.59.
