Question

the decimal which number lying between 2.2 and 2.22

Answer 1

Answer:  The answer is 2.21.

Step-by-step explanation: The two given decimal numbers are 2.2 and 2.22.

And we are told to find another decimal number between these two numbers. Let 'x' be a decimal number which lies in the middle of both of them on real line. Then, we have

$x-2.2=2.22-x\\\\\Rightarrow 2x=2.2+2.22\\\\\Rightarrow 2x= 4.42\\\\\Rightarrow x=2.21.$

Hence, 2.21 is a decimal number between the two given numbers. In this way, we can find as many decimal numbers as we wish between any two given decimal numbers.

Thus, the answer is 2.21.
