Jgn lupa pake cara nya yah:) Mohon di bantu

C = 5/9 (F-32)
C = 5/9 (68-32)
C= 5/9 x 36
C = 20 derajat celcius

R = 4/9 (F-32)
R = 4/9 (68-32)
R= 4/9 x 36
R = 16 derajat reamur

Dik:68°f
Dit:F=...°C
F=...°R
Jawab:
[tex]c = \frac{5}{9} (f - 32) \\ = \frac{5}{9} ( {68}^{o} - 32) \\ = \frac{5}{9} ( {36}^{o} ) \\ = {20}^{o} c[/tex]
[tex]r = \frac{4}{9} (f - 32) \\ = \frac{4}{9} ( {68}^{o} - 32) \\ = \frac{4}{9} ( {36}^{o} ) \\ = {16}^{o} r[/tex]
