To estimate the value of 6×2–√, we can make an approximation by substituting the value of √2 as approximately 1.41.

6×2–√ becomes 6×2–1.41.

Simplifying further, we get 12–1.41 which is approximately 10.59.

Therefore, the best estimate would be "10.6" since it is the closest choice to 10.59.

To determine which statement is true about the square root of 28, we can estimate its value.

The square root of 28 is between the square root of 25 (which is 5) and the square root of 36 (which is 6). Since 28 is closer to 25, it can be concluded that the square root of 28 is between 5 and 6, but probably closer to 5.

Therefore, the true statement is: "It is between 5 and 6, probably closer to 5."

The true statement about the integer fraction that equals the square root of 2 is: "It does not exist."

The square root of 2 is an irrational number, which means it cannot be expressed as a fraction of two integers.
