Answer 1

a) The halfway number is $\frac{-4.5}{10}$.

b) The ascending order is $\frac{-1}{2}$,$\frac{-4.5}{10}$and $\frac{-2}{5}$.

Step-by-step explanation:

a)Halfway number is otherwise Middle number.

The halfway number of two numbers = $\frac{sum of two numbers}{2}$.

The halfway for $\frac{-2}{5}$ and $\frac{-2}{5}$ = $\frac{\frac{-2}{5}+ (\frac{-1}{2})}{2}$.

=$\frac{-2}{5}+ (\frac{-1}{2})$.

= $\frac{-4-5}{10}$.

=$\frac{-9}{10}$.

∴Halfway =$\frac{\frac{-9}{10} }{2}$.

=$\frac{-4.5}{10}$

The halfway for $\frac{-2}{5}$ and $\frac{-1}{2}$= $\frac{-4.5}{10}$.

b) The ascending order is $\frac{-1}{2}$,$\frac{-4.5}{10}$and $\frac{-2}{5}$.
