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

Aug 12, 2016

The number is $0.2$.

#### Explanation:

The gap between $- 3$ and $5$ is $5 - \left(- 3\right) = 5 + 3 = 8$.

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

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

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