Take any irrational number - e.g., square root of 2, cubic root of 5, pi, e, etc. - and divide it by an integer (1) that is large enough, so that the result is smaller than the difference (which in this 0.2). Add that to 7.7.Note 1: Actually, any rational number will do here.

and so on.
Similarly, between any two of these there are infinitely many rational numbers.

Rational, 7.7 is 7 7/10, or 77/10.
77 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
78 - 89 are the numbers that come between 77 and 90.

A rational number is one that can be expressed as a ratio or a fraction: 1:5, 2/7, 23/77. An irrational number cannot. If you can write it as a decimal which ends or repeats, it is rational. Typical irrational numbers are things like pi (3.1415926535...), e (2.71828...), and most square roots (root 2 = 1.4142...).

Which two integers is the irrational number √77 between?
It can be written as a fraction, so it is rational.
77 is not a perfect square. Another way to look at it is this (use a calculator) sqrt(77) ~= 8.774964387 Notice how there is no point where the numbers begin to repeat themselves (e.g., 1.222322232223) Both reasons tell us that sqrt(77) is an irrational number. ----------- Yes - the square roots of all non-perfect square integers (ie the numbers which are 1², 2², 3², ...) are irrational.
Irrational
77 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
the real numbers between 66 and 77 are (66,67,68,69,70,71,72,73,74,75,76,77)
78 - 89 are the numbers that come between 77 and 90.

Nothing can fall "between 77". 77 is one number; you need an interval for any numbers to fall BETWEEN.
