Question

find 10 rational numbers between 2/5 and -3/5

Answer 1

$\frac{2 \times (10 + 1)}{5 \times (10 + 1)} = \frac{22}{55} \\ - \frac{3 \times (10 + 1)}{5 \times (10 + 1)} = - \frac{33}{55}$

the 10 rational no between 2/5 and -3/5 is

$\frac{23}{55} \frac{24}{55} \frac{25}{55} \frac{26}{55} \frac{27}{55} \frac{28}{55} \frac{29}{55} \frac{30}{55} \frac{31}{55} \frac{32}{55}$
