Radiation machines, used to treat tumors, produce an intensity of radiation that varies inversely as the square of the distance from the machine. at 3 meters, the radiation intensity is 62.5 milliroentgens per hour. what is the intensity at a distance of 2.7 meters? the intensity per hour. (round to the nearest tenth as needed.)

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?
