Question

list one rational and irrational number between 2.3 and 2.31

Answer 1

since, we know that
Rational no. =a+b/2
it means : a{a+b/2{b
so,
2.3+2.31/2 = 4.61/2
Hence the rational no. is 7/2 lie between 2.3 and 2.31
since, we know that
Irrational no. =√a×b
it means : =√2.3 × 2.31
=√5.313
=√2.3 × 2.31
= 1.51√2.31
Hence the irrational no. is 1.51√2.31 lie between 2.3 and 2.31.
