0.27 ÷ 0.03 = 9.

think of it this way it's like doing 27 ÷ 3 so you get your answer which is 9.

but then you see.
9×3 =27.
9× 0.3 =2.7

so that must mean
9×0.03 = 0.27.

you basically move the decimal point in this one and it's moved 2 or 3 times in this one

To do this, you must first multiply each one by a 100. Doing this, you get 27 and 3. Find the quotient and that is 9. Add me as a friend I am great with math.
