We are given expression i - 0.3i.

i can be written as 1i because when we don't have any number in front of a variable, the coefficent is 1.

i represents imaginary number there.

Therefore, we need to subtract 1i - 0.3i.

In order to subtract 1i-0.3i, we need to subtract 0.3 from 1.

We get 1-0.3 =0.7.

Therefore,  i - 0.3i = 0.7i.
