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.
All fractions are rational numbers because irrational numbers can't be expressed as fractions

All integers are rational numbers.
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.

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.
2.4494897Answer 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.

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!
