Solve this one in exactly the same way as I solved the one
that you posted 1 minute before this one.

-- add up all the ' r 's .

-- add up all of the just-plain-numbers

This time, the answer looks like 9r .

You should spend a few minutes with it so that
you know where this answer comes from.

alisha [4.7K]

Answer:

7 : 1

Step-by-step explanation:

Paul's car goes 40 kilometers on 7 tanks.

Distance : Tanks

49 : 7

Fuel efficiency means the distance traveled by the car in one tank.

Therefore, we will reduce the ratio by dividing both sides by 7.

Distance : Tanks

$\frac{49}{7}$ : $\frac{7}{7}$

7 : 1

Therefore, car's fuel efficiency is 7 kilometers in one tank or the ratio between Distance traveled and fuel tanks is 7 : 1.
