Question

If a and b are two rational numbers, then:

(a) (a+b)/2 < a
(b) (a+b)/2=a
(c)(a+b)/2 lies between a and b
(d) (a+b) /2

Answer 1

Step-by-step explanation:

Answer

The rational number between a and b is (a + b)/2

Hence rational number between 1 and 2 is (1+2)/2 = 3/2 = 1.5

Rational number between 1 and 3/2 is [1+(3/2)]/2 = 5/4 = 1.25

Rational number between 1 and 5/4 is [1+(5/4)]/2 = 9/8 = 1.125

Rational number between 3/2 and 2 is [(3/2) + 2]/2 = 7/4= 1.75

Therefore four rational numbers between 1 and 2 are 9/8, 5/4, 3/2, and 7/4
