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.
Rational, 7.7 is 7 7/10, or 77/10.
3.3333
The square root of 100 is 10, and it is a rational number.
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.
A decimal representation of a rational number which lies between 10 and 11.
