Question

find five rational numbers between -9 and -13

Answer 1

Rational numbers between -9 and -13 are

[(-9)+(-13)]/2=-11

[-11+(-9)]/2=-10

[-11+(-13)]/2=-12

[-10+(-11)]/2=-21/2

[-11+(-12)]/2=-23/2

∴ rational numbers between -9 and -13 are-11,-10,-12,-21/2,-23/2

(There are so much rational numbers between -9 and -13)
