..ответ: А) 4 1/2..---

Answer 2

To solve this problem, we need to multiply the mixed number 7/9 by each of the given options (A, B, and C), and then compare the results to find which one is closest to 8:1.

First, let's convert 8:1 to a mixed number: 8:1 = 8 + 1 = 8 1/1

Now let's convert 7/9 to a mixed number: 7/9 = 0 7/9

Next, we'll multiply 7/9 by each of the options:

A) 4 1/2 = 4 + 1/2 = 4.5 0 7/9 * 4.5 = 0 31.5/9

B) 4 2/3 = 4 + 2/3 = 4.666... 0 7/9 * 4.666... = 0 28/9

C) 3 3/4 = 3 + 3/4 = 3.75 0 7/9 * 3.75 = 0 26.25/9

Now let's convert the fractional parts back into mixed numbers:

0 31.5/9 = 3 6/9 = 3 2/3 0 28/9 = 3 1/9 0 26.25/9 = 2 9/9 = 3

So, the option that is closest to 8:1 (or 8 1/1) is option A) 4 1/2, as it results in 3 2/3, which is the closest to 8 1/1.
