8. Find three different irrational numbers between the rational numbers 5/7 and 9/11 .

Question:

Find three different irrational numbers between the rational numbers 5/7 and 9/11 .

Answer:

Decimal representation of rational number 5/7

Now, decimal representation of rational number 9/11

The required irrational numbers will lie between 0.714285 and 0.81. Also, the irrational numbers have non-terminating non-recurring.

∴ Required three irrational numbers are:

0.75075007500075000075..., 0.7676076007600076...... and 0.80800800080000...
