Question

Please help 20% of 3km = ?

Answer 1

600 meters

Cause if you find multiples of 30 (for meters of course) 6 goes into it 5 times, which a fraction for 20%=1/5. So if you multiply 6 by 5 you get 30. After you can just add 2 zeros to the equation and its the same thing, But Just in bigger numbers.

Feel free to correct anything wrong. I wouldn't mind changing the answer if its wrong. :)
