Question

find three rational number between 1/2 and 1/5​

Answer 1

Step-by-step explanation:

Let me understand the question a little better. Your objective is to find any two rational numbers between 1212 and 1515 . Okay, if my understanding is correct, I will take the mean of the two numbers.

1st number xx , where 15≤x≤1215≤x≤12

x=12+152=720x=12+152=720

Now we have three numbers. We need to find our second number yy in the range 15≤y≤1215≤y≤12

But notice that 720720 is the mean of the two numbers we just used. So if we take the mean of the three numbers now, we obtain 720720 (you can check).

Let us use any of the numbers between 1212 and 1515 and take its average with the new number 720720 .

y=12+7202=1740y=12+7202=1740

and you can check now

15=0.215=0.2

720=0.35720=0.35

1740=0.4251740=0.425

12=0.5
