a truck uses 8L of gas to go 120 kkkm. how much gas does it use to go 300km?

8 * 300/120 = 20

I'm assuming "kkkm" was a typo

could you do it like 8/120*300?

To think of it logically, the proportions remain the same.

8/120 = X/300

Then X = 8/120 * 300

I hope this helps a little more. Thanks for asking.
