Answer 2.
The number above is indeed rational, but it is not between root 2 and root 3.
To find a rational number that is in the range, calculate the two roots and write them down. Then write down any terminating decimal that is larger than root 2 and smaller than root 3. Bingo.
See lemma 1.2 from the cut-the-knot link. Yes, you can.
All the whole numbers or integers between 6 and 28 are rational numbers because they can be expressed as improper fractions as for example 7 = 7/1 but the square root of 7 is an irrational number because it can't be expressed as a fraction.
find all the square numbers between 1500 and 1800
The one thing they have in common is that they are both so-called "real numbers". You can think of them as points on the "real number line".Both are infinitely dense, in the sense that between any two rational numbers, you can find another rational number. The same applies to the irrational numbers. Thus, there are infinitely many of each. However, the infinity of irrational numbers is a larger infinity than that of the rational numbers.
If you are expected to calculate it without a calculator then the first step is to write the fraction as a ratio - a top heavy one if necessary. You will find that the numerator and denominator of the rational fraction are both perfect square numbers. Then the square root of the ratio is the ratio of the square roots.For example, to find the square root of 11.11... recurring.You know that, since it is a recurring decimal, the number is rational.In ratio form, this number is 100/9 and sosqrt(11.11...) = sqrt(100/9) = sqrt(100)/sqrt(9) = 10/3 = 3.33... recurring.

Find the arithmetic average of the two rational numbers. It will be a rational number and will be between the two numbers.
Add them together and divide by 2 will give one of the rational numbers between two given rational numbers.
There exists infinite number of rational numbers between 0 & -1.
A rational number is one that is the ratio of two integers, like 3/4 or 355/113. An irrational number can't be expressed as the ratio of any two integers, and examples are the square root of 2, and pi. Between any two rational numbers there is an irrational number, and between any two irrational numbers there is a rational number.
Yes. Take the average of the two numbers. Since those two numbers are rational, their average will also be rational.
There are an infinite number of rational numbers between any two rational numbers. And 2 and 7 are rational numbers. Here's an example. Take 2 and 7 and find the number halfway between them: (2 + 7)/2 = 9/2, which is rational. Then you can take 9/2 and 2 and find a rational number halfway: 2 + 9/2 = 13/2, then divide by 2 = 13/4. No matter how close the rational numbers become, you can add them together and divide by 2, and the new number will be rational, and be in between the other 2.
Suppose the two rational numbers are x and y.Then (ax + by)/(a+b) where a and b are any positive numbers will be a number between x and y.
All fractions are rational numbers because irrational numbers can't be expressed as fractions
All integers are rational numbers.

No. a set of numbers is dense if you always find another number in the set between any two numbers of the set. Since there is no whole number between 4 and 5 the wholes are not dense. The set of rational numbers (fractions) is dense. for example, we can find a nubmer between 2/3 and 3/4 by averaging them and this number (17/24) is once again a rational number. You can always find tha average of two rational numbers and the result is always a rational number, so the ratonals are dense!
