3 times that of the celsius = 80°F
1/ 3 times that of the celsius = -160°F/29 F
Fahrenheit scale = 9/5 (°Celcius) +32
a) 3 times that of the celsius
F = 3C
C= F/3
Fahrenheit scale = 9/5 (°Celcius) +32
= 3F/5 + 32
F - 3F/ 5 = 32
2F/5 = 32
2F = 160
F = 80° F
b) 1/ 3 times that of the celsius
F = 1/3 C
3F = C
F = 9/5( 3F) + 32
F = 27F/5 +32
5F-27F = 160
-22F = 160
F = -160°F/ 29
