Question

for rational number x and y the number that always lies between x and y is​

Answer 1

Here's your answer

For rational number x and y the number that always lie between x and y will be

$\frac{x + y}{2}$

for example, to find rational numbers between 10 and 11 we have to use the formula

$\frac{x + y}{?2}$

OK, so

$\frac{10 + 11}{2}$

$\frac{21}{2}$

so we can find as many rational numbers we want using this formula
