Question

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.

Year ~ 1958 / 1964 / 1965 / 1978 / 2002
Difference From Base ~ 0.10 / -0.17 / -0.10 / 1/50 / 0.54



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 < 50°C < 1/50°C

Answer 1

The answer would be B.

Explanation:

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.
