Question

find rational number between -4/9 and 2/9

Answer 1

$\frac{ - 4}{ 9} = \frac{ - 4 \times 1}{9 \times 1} = \frac{ - 4}{9}$
$\frac{2}{9} = \frac{2 \times 1}{9 \times 1} = \frac{2}{9}$
here we make the denominators equal.we are getting many numbers in between.
so
$\frac{ - 5}{9} \frac{ - 6}{9} \frac{ - 7}{9} \frac{ - 8}{9} \frac{ - 9}{9} \frac{1}{9}$
are the rational numbers
