Answer 1

Answer:

10 degrees Celsius - 2.5 degrees Celsius=7.5 degrees Celsius

7.5 degrees Celsius - 2.5 degrees Celsius = 5 degrees Celsius

5 degrees Celsius - 2.5 degrees Celsius = 2.5 degrees Celsius

2.5 degrees Celsius - 2.5 degrees Celsius = 0 degrees Celsius

0 degrees Celsius - 2.5 degrees Celsius = -2.5 degrees Celsius

-2.5 degrees Celsius - 2.5 degrees Celsius = -5 degrees Celsius

-5 degrees Celsius - 2.5 degrees Celsius = -7.5 degrees Celsius

-7.5 degrees Celsius - 2.5 degrees Celsius = - 10 degrees Celsius
