According to research: the mass that a person can lift on the earth is (1/6) of the mass that can be lifted on the moon, and the mass that can be lifted on Mars is (4/9) of the mass that can be lifted on the moon ). If American astronaut Mark in the movie "The Martian" can lift a weight of 240 kilograms on Mars, how many kilograms of weight can he lift on Earth?
据研究：人在地球上能举起的质量是在月球上能举起的质量的(1/6)，在火星上能举起的质量是在月球上能举起的质量的(4/9)．如果电影《火星救援》中美国宇航员马克在火星上能举起重240千克的重物，那么他在地球上能举起多少千克的重物？
