Question

insert 4 rational numbers between the 1 and 2​

Answer 1

Answer:

Step-by-step explanation:

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

Answer 2

Answer:

6/5, 7/5, 8/5, 9/5

Step-by-step explanation:

LCM of 1 and 2= 1

If you need 4 rational no. then divide and multiply 1 and 2 with 5

i.e 1X5/1X5 = 5/5

2X5/1X5 = 10/5

4 rational no between 1 and 2 is:

6/5, 7/5, 8/5, 9/5
