notes

If we write `-1/10` as `-10000/100000` and `3/10` as `30000/100000` ,

we get the rational numbers `-9999/100000` , `-9998 / 100000` ,

..., `-29998/100000` , `29999/100000` , between `-1/10` and `3/10`.

For example :  Find a rational number between `1/4` and `1/2`.

`=>`  We find the mean of the given rational numbers.

`(1/4 + 1/2)÷ 2 = ((1+2)/4)÷2 = 3/4 xx 1/2 = 3/8 `

`3/8` lies between `1/4` and `1/2`.

This can be seen on the number line also.

We find the mid point of AB which is C, represented by `(1/4 + 1/2) ÷ 2 = 3/8`.
