Answer 2

It appears you've written a mathematical expression, but it's not entirely clear what you're asking. Let me try to interpret and answer it based on the information provided.

In the expression "2 : у = 2,5 : 1, 25," it seems you're comparing two ratios. Ratios are typically written in the form of a fraction or with a colon. The colon is often used to represent a ratio. Here's how I interpret your expression:

1. "2 : у" represents the first ratio.
2. "= 2,5 : 1" represents the second ratio.

To compare these two ratios, we can simplify them to a common form. Let's do that:

First ratio: 2 : у Second ratio: 2.5 : 1

Now, to make the second ratio consistent with the first, we can multiply both parts of the second ratio by 2 to get rid of the decimal:

Second ratio (simplified): 5 : 2

Now, we have two ratios in a comparable form:

First ratio: 2 : у Second ratio: 5 : 2

These two ratios can be compared as follows:

Is 2 : у equal to 5 : 2?

To determine if they are equal, you can set up a proportion and solve for у:

(2 / у) = (5 / 2)

Cross-multiply to solve for у:

2 * 2 = 5 * у

4 = 5у

Now, isolate у:

у = 4 / 5

So, the value of у that makes the two ratios equal is у = 4/5.
