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.
Yes, the square root of 77 is an irrational number. This is because 77 is not a perfect square, meaning it cannot be expressed as the square of a whole number. Therefore, its square root cannot be written as a simple fraction, which is the defining characteristic of irrational numbers.
77 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Well, friend, 77 is a rational number. You see, rational numbers are those that can be expressed as a fraction where the numerator and denominator are both integers. So, 77 fits that definition perfectly. It's a lovely, whole number that can be written as 77/1.
78 - 89 are the numbers that come between 77 and 90.
65.5
It can be written as a fraction, so it is rational.
Irrational
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.
Which two integers is the irrational number √77 between?

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.
65.5
Nothing can fall "between 77". 77 is one number; you need an interval for any numbers to fall BETWEEN.
