Answer 2

8 days

Explanation:

We are told in the question:

Carlos has 4/5 of a tank of fuel in his car. He uses 1/10 of a tank per day.

How many days will his fuel last?

1/10 of fuel = 1 day

4/5 of fuel = x

Cross Multiply

1/10 × x = 4/5 × 1

x = 4/5 / 1/10

x = 4/5 ÷ 1/10

x = 4/5 × 10/1

x = 8 days

His fuel lasts for 8 days
