There are infinitely many rational numbers between any two rational numbers - no matter how close you try to make them.
4/7 = 36/63 = 360/630
and
5/9 = 35/63 = 350/630
So 351/630, 352/360, ..., 359/630 are between the two.
As are 3511/3600, 3512/3600 etc
and 35111/36000, 35112/36000 and so on.

A rational number is any number that, when put into decimal form, terminates after a finite amount of digits OR begins to repeat the same pattern of digits. An easy way to find rational numbers is that any number that can be expressed in a fraction (1/2, 9/4, etc) of two integers.There is an infinite number of rational numbers between any two rational numbers. For example, say we have the numbers 1 and 2. What if you add them and divide by 2? Is that a rational number? Is it between 1 and 2? And to see that there is an infinite number of numbers between 1 and 2, take the number you just found, it is 3/2, now find a number between it and 2. You can keep doing this.
A rational number is a number that has a definite end. For example, pi is never ending and is therefore an irrational number. -4, however, has a definite end. This makes it a rational number.
Sometimes. The number '4' is real and rational. The number 'pi' is real but not rational.
If you mean 4/9 as a fraction then it is a rational number
The square root of 16 is 4 which is a rational number
