Question

insert two rational numbers between -1.3 and -1.2 and arrange in ascending order

Answer 1

rational between two number a and b = $\frac{a+b}{2}$
rational between two number -1.3 and -1.2 = $\frac{-1.3-1.2}{2}$
= $\frac{-2.5}{2}$
= -1.25
rational between two number -1.25 and -1.3 = $\frac{-1.3-1.25}{2}$
= $\frac{-2.55}{2}$
= -1.275
therefore the two rational number is -1.25 and -1.275

acsending order of the four number is -1.3 , -1.275 , -1.25 , -1.2
