Answer 1

Ответ:ответ равен *19,56*

Answer 2

To simplify the expression, let's solve it step by step.

First, let's simplify the expression on the left-hand side of the equation:

7:25 + 1/3 : 5/24 - 22/25

To add or subtract fractions, we need to have a common denominator. The common denominator for 25, 3, and 5 is 75. Let's convert all the fractions:

(7/25) + (1/3)(24/24) - (22/25)(3/3)

7/25 + 24/75 - 66/75

Now, let's combine the fractions:

(7/25) + (24/75) - (66/75) = (7 + 24 - 66) / 75 = -35/75 = -7/15

Now let's simplify the expression on the right-hand side of the equation:

(4,5 + 2/5) : (7/20)

The number "4,5" seems to be a typo, as it should be "4.5" or "4 1/2." Assuming it's "4.5," we can simplify further:

4.5 + 2/5 : 7/20

To divide fractions, we invert the second fraction and multiply:

4.5 + (2/5) * (20/7)

4.5 + (40/35) = 4.5 + (8/7)

Now, let's find a common denominator:

(4.5*7/7) + (8/7) = (31.5/7) + (8/7) = (31.5 + 8) / 7 = 39.5 / 7

Dividing 39.5 by 7 gives us approximately 5.64:

39.5 / 7 ≈ 5.64

Therefore, the simplified expression on the right-hand side is approximately 5.64.

In summary, the simplified equation is:

-7/15 = 5.64
