Ms. Morgan's class studied the changes in average global temperature in math class as a part of their study of rational numbers. The table shows how each year varies from a base measure.


Order the five years from coldest to warmest.


A)-0.17°C, -0.10°C, 0.10°C, 0.54°C, 1/50°C


B)-0.17°C, -0.10°C, 1/50°C, 0.10°C, 0.54°C


C)-0.10°C, -0.17°C, 0.10°C, 1/50°C, 0.54°C


D)0.10°C, -0.17°C, -0.10°C, 1/50°C, 0.54°C

Verified Answer :

B because 1/50 degrees Celcius is 0.02. The order would be -0.17,-0.10,0.02,0.10,0.54,which is B. Or you can order it in years: 1964,1958,1978,1965,2002.
