Question

1 rational no. between1.3 and 1.4

Answer 1

To find,

one rational number between 1.3 and 1.4

we know, rational number is a number that can be expressed as P/Q, where P and Q are integers but Q ≠ 0.

first write decimal number into fractional ( i.e , rational)

1.3 = 13/10

1.4 = 14/10

we can write 13/10 = 26/20

and 14/20 = 28/20

now between 26 and 28 , only one number i.e., 27

so, 27/20 is a rational number that lies between 26/20 and 28/20.

now, 27/20 into decimal ⇒ 13.5/10 = 1.35

Therefore 1.35 is a rational number that lies between 1.3 and 1.4
