Yes. -10 = -10/1 which is of the form of one whole number over another whole number. Rational numbers have the form of one whole number over another whole number. Thus -10 is rational.
There are infinitely many rational numbers between them. One example is 9.00000000000246064000000002
Yes, 3.4 is a rational number between 3 and 4: 3.4 is between 3 and 4, and 3.4 = 34/10 = 17/5 which is a rational number. The rational number midway between 3 and 4 is 3.5
Infinite. A rational number is any number that can be expressed as the quotient of two integers, so -500,000,001/50,000,001 is a rational number slightly greater than -10. Strangely, there are even more irrational numbers, which are also infinite. Ow. My brain always hurts on that one.
An infinite number
10 is a rational number.
Between any two different real numbers, there are infinitely many rational numbers.

There is no "the" rational" number since there is an infinity of them. Start with the number halfway between the two: (1/10+1/11)/2 = 21/220. Then try halfway between 1/10 and 21/220, and then halfway between 1/10 and that on. And so on.
The square root of 100 is 10, and it is a rational number.
A decimal representation of a rational number which lies between 10 and 11.
It is 10 which is a rational number.
