8 days.

Explanation:

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 :)
