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.
