In 2016, the car sales volume in China reached 24 million, and the fuel consumption of cars has a very important impact on car sales. Various car manufacturers are actively adopting new technologies to reduce fuel consumption. A car manufacturer surveyed 1,200 car owners to investigate the fuel consumption of a certain model of car. According to statistics, the average fuel consumption of this model of car is 8.0 liters per 100 kilometers, and the fuel consumption of the car $ξ$ follows a normal distribution $N(8, s^{2})$. It is known that the probability of fuel consumption $ξ∈[7,9]$ is 0.7. Therefore, the number of cars with fuel consumption greater than 9 liters is approximately $\_\_\_\_\_\_\_\_$.
