8 days.

First, I'm going to convert $4/5$ to a number that works with $1/10$ . All i'm going to do is multiply the numerator and denominator by $2$ .

$4/5 xx 2/2 = 8/10$

If Carlos uses $1/10$ of fuel everyday. Assuming it's $1/10$ of the max, not the current fuel, he will last 8 days.

Hope this helps :)
