Answer:
the rational number between 31.5 and 31.6 is 31.55
Explanation:
Now, we know that, average of the given numbers will lie in between the given numbers.
And, as we are finding average, which means sum divided by 2, it can be written in
form.
So, it will be an rational number between given numbers.
Then, average of 31.5 and 31.6 =
![((31.5 + 31.6 ))/(2)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/td74u6shlirt1d3h56jbn2j1fhouf75pyx.png)
Average =
![(63.1)/(2)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/7v3tu2ijlegecp1kksdkh4qfxpsasg4ugn.png)
Average = 31.55
