I'll do problem 1 to get you started.
something * 0.05 = 0.04
To isolate the "something", we need to undo what is happening to it.
We need to undo the multiplication.
To undo multiplication, we divide both sides by 0.05
something = 0.04/0.05 = 4/5 = 0.8
As a check,
0.8 * 0.05 = 0.04
0.04 = 0.04
which confirms we have the correct value to fill in the blank.
Problems 2 and 3 will follow a similar pathway.
