Question

Find a number `2/5` way up from `-3` to `5`?

Answer 1

The number is `0.2`.

Explanation:

The gap between `-3` and `5` is `5-(-3)=5+3=8`.

Hence from `-3` to `5`, it is `8` units up.

If we have to find a number `2/5` of the way up, it is `8×2/5=16/5=3.2` units up.

Hence the number is `-3+3.2=0.2`.
