Question

using mean method ,find a rational number between -8upon 9 and 9upon8​

Answer 1

Answer:

Ok so to find the mean of these two numbers you need to add them up and then divide by 2.

So first add -8/9 and 9/8

(Hint LCM is 72 so the two fractions will become -64/72 and 81/72 respectively)

The sum of these 2 numbers will be 17/72.

Now divide by 2.

You will finally get 17/144 (cannot be simplified).
