Answer 2

You have 10 cars. Each car needs 1 1/5 liters of oil.

\[cars(liters) = total. \]

So what you want to do is convert 1 1/5 into 6/5

\[cars(\frac{ 6 }{ 5 }) = total. \]

Then plug in the number of cars.

\[10(\frac{ 6 }{ 5 }) = ?\]

Simply multiply THEN simplify and you have the answer. :)

Answer 3
