Question

How do we know rational number that’s between number 4 and 6

Answer 1

Hi. To find one rational number between two given rational numbers, we have a formula as below:

$\dfrac{a+b}{2}$

where, a and b are the two rational numbers.

Thus, a rational number between 4 and 6 will be

$\dfrac{4+6}{2}\\\\\\= \dfrac{20}{2}\\\\\\= \large \underline{\boxed{\boxed{\bold{10}}}}$

Hope it helps.
