Question

find five rational number between 1and 2 in the formula of x+y÷2​

Answer 1

hey mate...

here is your answer...

1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9

Take any five…

Method:

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

Rational number between 7/4 and 2 is [(7/4) + 2]/2 = 15/8 = 1.8  

Therefore five rational numbers between 1 and 2 are 9/8, 5/4, 3/2, 7/4 and 15/8.

hope it helps...
