A scientist looks at a bacterium and a virus in a lab. The bacterium has a diameter of 10 Superscript negative 6 meters. The vir
us has a diameter of 10 Superscript negative 7 meters. Which statement accurately compares the sizes of the specimens? The diameter of the bacterium is 10 times greater than that of the virus. The diameter of the bacterium is StartFraction 1 Over 100 EndFraction times as great as that of the virus. The diameter of the virus is 10 times greater than that of the bacterium. The diameter of the virus is StartFraction 1 Over 100 EndFraction times as great as that of the bacterium.
25/80 + 24/80 = 49/80. 16 and 20 both go into 80. !6 goes in 5 times so you multiply 5 by 5. 20 goes into 80 4 times so you multiply 4 by 4. 24/80 + 25/80 = 49/80.
