The number is $0.2$ $0.2$ .

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

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

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

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