What ?  What ? 
Did you write the first two answers in pencil ?
They're correct !  Just do the other two exactly the same way.

-- Do the division problem printed in the "Distance ..." column.

-- Multiply the answer by  0.1 .

-- Write the new answer in the last column.

Ibelieve 4mn because it’s like you’re combining them
