Carlos has fuel that is required for 8 days.
Step-by-step explanation:
Carlos has 4/5 of a tank of fuel in his car.
He uses 1/10 of a tank per day.
Fuel is required for = \(\frac{4}{5}\) ÷ \(\frac{1}{10}\)
Now we reciprocate the fraction
\(\frac{4}{5}\) × \(\frac{10}{1}\) = 8 days
Carlos has fuel that is required for 8 days.
