Convert ­4οF to degrees Celsius.
C = 5/9 (F ­ 32) = 5/9 (­4 ­ 32)
= 5/9(­36)
= ­180/9
= ­20

Convert 78οF to degrees Celsius.
C = 5/9 (F ­ 32) = 5/9 (78 ­ 32)
= 5/9(76)
= 230/9
= 25.6

Convert 39οC to degrees Fahrenheit.
F = 9/5 C + 32
= 9/5(39) + 32
= 9/5 x 39/1 + 32
= 351/5 + 32
= 70.2 + 32
= 102.2

Convert 14οC to degrees Fahrenheit.
F = 9/5 C + 32
= 9/5(14) + 32
= 9/5 x 14/1 + 32
= 126/5 + 32
= 25.2 + 32
= 57.2
