. Find the four rational numbers between 1 and 2

Best Answer

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.

Final Answer:

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