Answer:
-6.25 °C < 6.55 °C < 12.5 °C is the order of the temperatures from least to greatest.
Step-by-step explanation:
Temperatures recorded here for Science Project = 12 1/2 °C, 6.55 °C, and -6 1/4 °C
Now, 12 1/2 °C = 12.5 °C
6.55 °C is already in decimal form.
and -6 1/4 °C = -6.25 °C
Hence, the ascending order of the temperature is
-6.25 °C < 6.55 °C < 12.5 °C where
-6.25 °C = Least Temperature , 12.5 °C = Greatest Temperature
