1. C:(F-32) = 5 : 9
C=5x(F-32)/9
C=5x18/9= 10°C

2. R:(F-32)=4:9
R= 4x (F-32)/9
R= 4 x 45/9= 20°R
3. C= K-273
C= 225-273= - 48°C
F-32:C=9:5
F-32= -48x9/5
F=-86.4+32= -54.4°C

1. 14 F =... C. jawabnya, C = 5/9 (F-32)
jadi, C= 5/9 (14-32)= 5/9 (-18)= -10

2. 77F=...C jawabnya sama seperti nomor 1
jawabnya = 25C

3. 225K= ...F
yang ini kita ubah dulu ke C. 
caranya C= K-273
C= 273-225= 48

F=9/5 (C+ 32)
F= (48+32)9/5= (80.) 9/5= 144 F
