Step-by-step explanation:
5/7 < 9/11
Square both to get
(25/49) < (81/121)
----------------------
Least common multiple of the fraction denominators is 81*121 because they
share no factors.
---------------------
Rewrite the fractions as
((25*121)/(49/121)) < (81*49)/(81*49))
Simplify to get:
3025/5929 < 3969/5929
-------------
pick some numbers between 3025 and 3969
like 3127, 3255, 3659
------------------------
Form the fractions: 3127/5929, 3255/5929, 3659/5929
----------------------
Take the square root of each:
sqrt[3127/5929], sqrt[3255/5929], sqrt[3659/5929]
------------------------
Each of these will be irrational numbers between 5/7 and 9/11
